The "unique" functionality is not going away, it's just going to be implemented in a \
different way with Qt5/KF5, and it looks like porting away from KUniqueApplication \
would be quite straightforward:

http://community.kde.org/Frameworks/Porting_Notes#KDEUI_Changes
http://api.kde.org/frameworks-api/frameworks5-apidocs/kdbusaddons/html/classKDBusService.html


I still think that making Dolphin a KUniqueApplication makes sense, I just did not \
get round to do it (a simple git revert of \
http://quickgit.kde.org/?p=kde-baseapps.git&a=commit&h=fff7573ebb910712ad97951bf1762e6a7bb0bdc7 \
does not work).

handle all drag&amp;drop-related messages is good. However, if we had more than one \
DolphinMainWindow per process, it would cause each message to be shown in all \
windows, right?

Dolphin did use a single process for all windows before KDE SC 4.7. That was changed \
because Strigi caused Dolphin to crash a lot at that time, and it was quite annoying \
to see all Dolphin windows disappear if one of them crashed. Moreover, the \
application-modal KIO dialogs caused all Dolphin windows to freeze if a dialog was \
shown for one of them. There were some discussions about this issue recently, see, \
e.g.,

http://lists.kde.org/?t=137537235900004&amp;r=1&amp;w=2

Dolphin is much more stable now than it used to be, and the KIO dialogs are now \
window-modal thanks to Dawit&#39;s efforts:

https://git.reviewboard.kde.org/r/114473/
https://git.reviewboard.kde.org/r/114436/

Therefore, we could actually make Dolphin a KUniqueApplication again in 4.13. One of \
the benefits would be that opening a new Dolphin window would be very fast if the \
&#39;dolphin&#39; process is running already. It might not be quite as easy as \
reverting

According to KF5 API docs, KUniqueApplication is only kde4support.

Should we really rely on it in the 4.x era, given that KF5 is almost ready to start \
