I just noticed that under my panel sub menu, there are no entries after I upgraded to 4.5 from 4.4.4. Also, the embedded terminal option seems to be gone, it now only fires off an external Konsole. I really used that feature a lot and it was very handy.
I did remove the ~/.kde4/share/config/dolphinrc file but that didn’t change anything, except get rid of the panels I had set as defaults previously, so I moved my original back.
I just tried the F4, if I do that, then the embedded terminal does appear, didn’t remember that. I used to be able to set it in the customize toolbars setting, but now that only appears to have the external konsole launch as an option.
then start dolphin and set it up your way, the missing features should be back.
i suspect that other applications really don’t upgrade cleanly, but i haven’t noticed anything else yet. Btw, on my machine, the dolphinpartrc file was not recreated and either i haven’t used the feature requiring it or it is not needed anymore.
