@pes10k feel free to share your thoughts, maybe there is a better naming scheme for the feature/components/etc.
Here is how the UI part looks now: brave/brave-browser#14127 (comment)

[goodov]

Made it in alphabetical order. Shouldn't break anything, but if someone thinks the other way, please say it.

[pes10k]

@goodov i think the change looks good, but that it might be best to wait for @karenkliu before committing any UI changes, in case she (or others on the design team) think something other than a drop down is best

[iefremov]

@bridiver PTAL ?

[goodov]

@mkarolin could you please take a look at the changes as a patch-reviewer?
