qgit does not intergarte Kompare functionality, it just prepares the files and spawns a Kompare process.

So there's seem nothing qgit can do about Kompare speed. You can try with different diff viewers, meld,...etc..

Well temporary file sfor Kompare are created in the repository working directory. If this is a problem for you you can save manually the files corresponding to the two revisions you want to diff (open tree view, select the file, right click to open context menu, save as...)

You need to repeat the above 'save as...' the first time selecting the first revision you want to compare, then selecting the other revision in main view, so that tree view is updated and you end-up saving the correct files.

You can save the files where you want then run Kompare manually, at least you test your assumption about slowness of NFS partition.

If you can post a repository where this occurs and the step to reproduce I can investigate further.

Yes. This is true, is not supported this feature. Maybe could be added ;-)

Please install 1.5.7, it has several bugs fixed.

It does not interfere wuth Qt3 also if you install with urpmi, directories are kept separated. I have installed both with no problems.

Qt4 is big and complex, I would really suggest avoid experimenting with that library, stay safe and use urpmi.

In this case (and also in the above case of external viewer) you need the magic wand ;-)

Select a file from tree view, go with the magic wand and you can do everithing from main view.

Yes it is. qgit-1.5.7 should be very similar to qgit-2.0 regarding the features you listed above.
