Me and the fellas over at the #development discord channel have come up with a few improvements to the current client UI, these are my proposed changes and I'm open to any suggestions or feedback.
I feel like the current one is too "default-looking" and needs a bit of personality, in all my mockups bellow, a couple of changes I made were:

There was nothing wrong with the current version, I just wanted to apply some of the new design rules to make it more modern, get rid of the borders and use different shades of grey for contrast and separation, changes made were:

The hiscores panel had some issues, nothing to big, it just needed to be realigned with my new proposed look, a few changes were made:

Again, I think there is nothing wrong with the configs panel, just changed it a bit to match the rest of the design, changes made were:


Many people like this plugin as it is, I think it could be better, however I'm not sure I have the solution, either way, here's an attempt:

Personally I like it how it is currently but not like I have anything against your version so if I'm outvoted I won't complain too much =p
As for functionality I really only have one thing that I saw that needs addressing after a quick look through and thats the last thing you posted "XP Trackerplugin". The reset button imo needs to be at the top because if you have enough skills "open" it creates a scroll and I would rather not have to scroll to reset.
In addition to what Stickaplex said, instead of centering the reset all button, you could add another label showing your Total XP gained for this session, and keep the reset on the right if you wanted to
This looks nice
Here be my comments with the perspective of a web developer.
Really you should use the same user as a reference so we don't see a difference in data..
trippple+++;RE: Material switcher
I do like the toggle switches easier. The color difference is nice, though the value needs a bit more work.

I would like to completely redo the config panel, turning it into a pop-out window similar to IntelliJ's. I have some code on this, but not anywhere near a working prototype. However as it requires breaking changes to almost every plugin, I would like to delay it until Adam's trip is near it's end.
@Stickaplex I too think there's nothing "too" wrong with the current one, but don't let that ever stop you from trying to improve, if you feel like your attempts were unsucessful, just don't do it :P it's just a suggestion. But I do agree that the reset button should be at the top, I forgot the trackers would stack very high, will update my mockup in a second, thank you!
@LeviSchuck First of all thank you for the compreensive feedback, I have some things to say:
I just copied it off the current client, but good question. I have been working with the ge plugin to add some more functionality to it, so I may take a look at this.
Again, the API was down for quite a while so I couldn't get real data, my bad, will update this.
Yea I couldn't really figure out why they were using a blue star.
I did not understand what you mean't by the value.
# XP Tracker plugin
The label vs the value

The label is less important than the value, making the value harder to read makes it harder to use.
I understood that, that was your 4th point, I had doubts on the 3rd
The dark theme has too much of "OSBuddy" with itself. Imo if this is being considered, I'd vouch for actually creating your own custom themes / choosing community made themes. But not for solely this theme
Oh, I see.
Value in the sense of color theory. That's why I put up an image in gray-scale.

For those with diminished color reception and for view in the periphery, the value of the toggles needs more contrast.
@YasinY What do you have in mind? I suggested a light theme but it didn't get much traction, I think dark is the way to go, runescape is already very colorful as it is.
@LeviSchuck oh the gray-scale value, good catch, what is your suggestion? I just used the brand orange.

I suggest making the false value darker
@psikoi I'd agree with the dark theme when the alignments of the icons would change for example:

maybe make them horizontal instead of vertical (I'm talking about the icons on the right bar)
Because right now, the current theme reminds me too much of the osbuddy theme. (imo)
and also

instead of making the false value darker, make the true value rather greenish, it'll look more interactive imo
Updated the first post and applied some of the feedback from this comment section.
Also, another suggestion about the high alch issue, if it's 0, instead display N/A
so it's High alch: N/A instead of High alch: 0
I would love this to be a 2nd optional theme. It looks alot cleaner!
If this will be implemented it will replace the default one.
I really like this, but I don't think this is a priority? However I'd like to see it in the near future.
Edit; What I mean, if it's not too much of a work, implement it.
Well, one of the good things at being open source is that there is infinite number of people who can work on infinite number of things at once :D So, @psikoi working on this one as priority will not slow down any other progress in the client by the slightest.
Just a thought, what about trying to emulate osrs xp tracker? something like

(rs one for reference)

I guess this does make it look eerily similar to konduits
@sethtroll Actually I drew some last night that are very similar, except they don't have the info at the bottom.
It's a tricky game between clean ui and information display.

Did you have a redesign for the info panel in mind?
I threw something up real quick, not sure what else to put there

I hadn't yet, but now I do! a couple tweaks and it'll fit in real nicely, give me a few minutes.
@sethtroll what do you think of this?

Yeah looks good, could probably throw in current online players somewhere and also add a twitter link
The dream lives on, this suggestion has been developed and is awaiting approval and merging, planned to be merged on the 17th of May. 馃帀 馃帀
This should not be closed until the PR is merged
I'm new... how do you downbload this? or we can't?
@ely151 it will be in release this thursday after RuneLite updates.
