When I save a POT file which I opened from the project summary tree, the whole project summary tree starts refreshing. It must have something to do with the fact that saving a POT file basically creates a new PO file.

This is specially painful with KDE translations, because there are lots of files there. So if I want to translate several new short POT files in a row, I see myself having to wait a non-trivial amount of time between saving one of them and opening the next one. I end up opening all files at once in different Lokalize tabs as a workaround.
