In case you want to test, here a build: Keka-Czech.tar.7z

Hey @aonez! Thank you for the build, I found some minor typos in it that I fixed. I have a question though.

I'm a bit concerned about these labels being cut off:

I know there's this in Localizable.strings. Would setting it to any other value help, and if so, what are the recommended values?

I'll fix that one for you

Cool! You'll do another pull?

75.0 for _ADVANCED_EXTRA_WIDTH_ it is

[buresdv]

I'll do another pull in a few minutes with both the fixed typos and the correct _ADVANCED_EXTRA_WIDTH_ 😊

Can you send me another build after this next pull is merged so I can check everything again, to make sure everything looks good?

[aonez]

Sure @LFenix! Thanks again for this 😊
