Cleanup and resize UI elements

[Manhunter07]

When changing the language, most UI elements do not fit their caption inside, although it would perfectly fit if they had a sufficient size. Please fix this, either by making them autosize, or by giving them the required (or even, the most possible) size. This is not hard as the window's minimum size constraints are already wide enough for it to show all captions (at least for most languages, including German).

a simple restart would help

Confirming that this works (after switching from EN to pt_PT translation): the most possible size is used to fit after a restart.
Because apparently there is no FAQ suitable in the homepage, I'd then suggest this to be embed into the application itself. Mock:

Perhaps an even better alternative would be making a richer version of the text as a tooltip for the Language drop-down:
Translations apply at runtime, with minor constraints - in case visual artifacts or truncation is observed, please restart.
