While webuilder is really a great program, when working with it some time, i noticed three little quirks that keep disturbing me.
1) This is already in another thread, just to have it all together because it's the same topic: Tabs and whitespaces at the end of lines are removed by webuilder when selecting the line, causing the file to appear modified.
2) This is a quite serious bug in my opinion: if someone else has modified an open file, a dialog appears: "Another application has modified ... Do you want to load the updated version?"
This dialog should be modal!
Now, as soon as you click somewhere in webuilder, the dialog moves behind webuilder and you're allowed to change the file and even save it, overwriting the changes of the other person.
3) If a file which is already open is doubleclicked in file explorer, a dialog appears: "Do you want to revert to the last saved version?". IMHO this should (if at all) only appear when the files on disk and in the editor are really different, otherwise it's quite disturbing, suggesting the file has changed somehow after it was saved. And another one: if you answer "Yes", the file appears changed (asterisk), but it as was just opened from disk, it cannot possibly have been changed.
