Hello Todd,

For Dolphin and Konqueror related questions please use kfm-devel at I'll 
just give very short answers to give a rough indication what I as maintainer 
of Dolphin think about your input. For further discussions please open a 
custom thread per question on kfm-devel at Thanks!

I'm open for this idea, I think this might work well.

Selecting worked already in KDE SC 4.3 by clicking on the group header, 
deselecting did not work (is a bug IMO). Due to some refactoring of 
KCategorizedView by the class maintainer done for KDE SC 4.4, also selecting 
does not work anymore. I wanted to fix this myself (see bug 221902), but a +/- 
icon is not needed IMO. I would appreciate it if you could have a look on this 
issue (it is in KCategorizedView from kdelibs).

IMO not needed. Must be clarified with the maintainer of the class (this is 
out of scope of Dolphin).

I would not accept this patch for several reasons, but I don't want to provide 
a lengthy reasoning here on kde-core-devel.

I'd prefer that other issues with opening multiple files get fixed first (e. 
g.  selecting 100 images opening with Gwenview will open 100 Gwenview 
instances currently...).

We dropped the action panel from Dolphin in KDE 3 for some reasons for KDE 4 
and I don't want to reintroduce it again.

You're very welcome to contribute patches! From my experience I'd recommend to 
start with bugfixes instead of features. This makes you familiar with the 
codebase and gives a quick indication for yourself whether you are also 
willing to do the "no-fun" part of development when you need to do bug fixes 
for your custom features ;-)
