Very annoying glitches in the tab bar (tabs moving back and forth), every time when I mark some text e.g. for copying.

It does not list all the DeepL supported languages once i click the addon's icon. So i can not set my language. Can you improve this please?

Also it is causing erroneous blinking of the pages and the translation is opened on a new background tab instead of on-page pop-up/tooltip.
