I cannot translate typo.properties the string urlfixer.isItCorrect.
As soon as I type about 10 characters, the Commit Translation button disappears!?@
The issue is this comment box on the right. You can hide it but in the next moment it appears again. Then is more space for the other two boxes. I have a small screen. Also the filter button in the left box often disappears if there is no space enough.
With accesskeys it is terrible. I have to click all strings to find the right entity. Sometimes the string text helps but not always. It is better to have the string text of the related entity. I can look for the corresponding string then. Sometimes the label string has another name than the accesskey string. And if the file is big - i.e. has more than one page - you must search on several pages and the label string can be on another page than the accesskey string.
Maybe that crowdin is better than Babelzilla for extension authors but for translators Babelzilla is better. In Babelzilla I don't need click on all strings to find the correspondig entity. And nothing disappears. It is better to translate offline.
