Hello,
after long consideration I've finally get plasma5 and new KDE also I've switched to skrooge-kf5 2.0. The transition was seamless and awesome, considering data (wich was crucial). But on the other hand I've lost all my personal setting in skrooge (I know, I could have anticipated something like that). Problem is that not all of the settings are manageble by settings in application.
I've changed and added bank icons and locale settings for that banks and keep it in ~/.kde/share/apps/skrooge/images/logo/..... this path no longer applies to new skrooge
Also I'm a translator of skrooge for my native language and to test and view translations directly inthe application really helps. Thats why I need to know where theese user settings should be stored. I mean in my user directory so it won't get overwritten by reinstalling or upgrading.

Thanks

Since nobody is answering and I figure that a while ago, it would be rude of me to let it unaswered.
Like all the other stuff in kf5 the location is now ~/.local/share/skrooge/images/....
