Transmission Remote GUI 5.18.0

I second that, focus color needs a little change.
To make it a more complete example:

This is in the morning, when colors go from dark to light. It is the same mess in the evening when they go from light to dark.
Yep, MacOS Dark mode Font color adjustment really appreciated!
Same problem here.
same issue
On Mac OSX Mojave in Dark Mode using 5.18.0, everything looks good except "Text Area" field. They use black font over dark grey background.
Only problem I've seen is when things are disabled... The labels look odd

9 months and counting. Any active devs with the skill set to fix this and compile a dev build to share? I'd be very grateful as well as others, I'm betting.
here to report the same issues, hopefully someone will pick up the project and fix it!!
Update 10/27/20: To clarify, this only turns off _dark mode_ for this one app and leaves _dark mode_ applied for all other apps.
Here's a workaround that will disable _dark mode_ for the Transmission Remote GUI app so that you can at least see the Table GUI. Paste this into the terminal and press return:
defaults write com.transgui NSRequiresAquaSystemAppearance -bool yes
Then restart the Transmission Remote GUI app if it was already open.
To reverse this change in the future, paste this into the terminal.app and press return:
defaults write com.transgui NSRequiresAquaSystemAppearance -bool no
Hardly a workaround if it disables dark mode.
It only disables it for this particular application while leaving all others in dark mode. If your priority is to get the table to render properly, this is one method.

Assuming from the above that the application uses Lazarus for its interface, there's example code to detect light/dark mode changes, including automatic mode, here:
https://wiki.lazarus.freepascal.org/Dark_theme#Example_2_2
It came from discussion in this thread:
https://forum.lazarus.freepascal.org/index.php?topic=43111.0
I hope the app can be updated to respond to mode changes, currently you either have to restart the app twice a day or disable dark mode for it, neither of which are ideal. Am happy to help with any testing etc.
