Now the size of the edit window is fixed and not use all size it can¡t used.

I think could be more useable is you can maximizaced. You will wach more option easyly, and not need scrool in sections like subtitles.

Thanks for answer. I can see usuall maximiced button and I don't try it.    

With maximiced icons, it's possible no more people do the same mistaque I made.
