I shared this idea with Petr Vozak at the "ask an expert" session in the last Kentico Developer Connection...

I want to share with other people too and see what you think about it... Here's the idea:

In the UICultures panel, when you have to deal with 3 or more languages in your Kentico website , wouldn't be great if you can select the LABEL and not the language when you have to edit them? I mean, it will be great to have a single form to edit all the languages of a single translation label and avoid the time wasting action of switching back and forth some language!

With the new panel (in the attachment you'll find a way all of this can be done) you'll have a form with 3,4 or more input fields based on how many cultures you've enabled in your CMS Site Admin.
