A number of new clients have had issue with inconsistent action button labels, confirmation + warning dialog, different labels for the same thing etc. Has caused confusion and annoyance with some of them.
Referring to things like:
I'm happy to look at this but can I get some feedback first:
MODX all versions
To propose changes you'd use the same process as other contributions. Create a git branch, make and commit your changes, send a pull request. I'd recommend branching of 2.x and also sending your changes to 2.x, so these updates could be incorporated into 2.6/2.7.
The lexicon files are in https://github.com/modxcms/revolution/tree/2.x/core/lexicon/en. Having a search tool will help find where each entry is. ;)
Keep in mind lexicons are cached by default. Set cache_lexicon_topics to no so you wont have to clear the cache after each change.
The 'Delete' and 'Remove' labels are tricky; resources that are 'deleted' are just flagged in the database for deletion, while 'remove' actually refers to permanently deleting something from the database.
Not a simple task but I think it will come down to writing style and striking the balance between simple, consistent UX and technical accuracy.
Were in process of getting more formalised feedback from the clients that have raised these issues which will help a lot and material design will also influence the strategy. Some good reading:

@sottwell regarding remove and delete there is additionally the word "purge" being used...
What about we use something like this:
Another unnecessary terminology:
"Extras, add-ons, packages, components".
As I understand it, packages - is an installation archive for components.
The rest (extras, add-ons) is not clear to what applies.
Also sometimes referred to as "plugins", which is somewhat confusing since in MODX "plugins" refers to a specific type of extra, add-on, component.
Template Variable or TV.
It makes sense, when creating a TV, in the description above, to write both form of the TV title: full and the abbreviation. And then use only the abbreviated form of TV title in manager.
Settings
In the "Package Management" section, each package has the "Uninstall" and "Remove" buttons. But their names and actions are not entirely correct.
"Uninstall" sometimes means deleting, although in MODX it works like a downgrade to the previous version, it is better to call it "Downgrade".
"Remove" does not remove the package from the files unless the "Force Package Removal" checkbox is checked, although it should always remove.
It seems that the checkbox "Force Package Removal" is needed for emergency removal, as if the removal is not correct, and it confuses users.

It happens that the concepts of "Document" and "Resource" are used as one and the same, but this is not correct.
A "Document" is a resource with an HTML content type, and a "Resource" is a broader concept (link, static resource, etc.). It will be necessary to fix this in the lexicons.
I believe @rthrash isn't to keen about changing the "Document" and "Resource" terminology.
@JoshuaLuckers No, I do not mean that changes are necessary, but about the fact that in the lexicons these concepts are sometimes used incorrectly (text about resources, but the term documents is used).
By the way, the name "Resources" (tab in the tree) has the key "documents" in the lexicons, which also does not bring understanding.
In the topics files there are unnecessary entries, for example, "Edit TV", "Edit chunk" ("create_", "delete_" etc), but it is easier to use one "Edit" entrie for both TV, chunk and other element. Why such specific entries for the elements? There are not only extra lines in the topics, but errors in the code, i.e. used, for example, and "create" and "create_ELEMENT" at the same time, etc.
