Beside taking care to keep Dolphin simple and efficient for users, it is also very important for me to do the same for the code: It should be simple and easy to maintain for developers.
Sometimes this works quite well, but it also happens that parts of the code need to be refactored. It is quite common in commercial companies that developers don't get the chance to refactor the code: The user does not recognize it in the first sight and there is definitely a risk of having regressions.
I'm convinced that in the long-term keeping the code base clean pays off and results in less bugs and easier maintenance. Although some features like improved searching or version control support have been added for Dolphin in KDE SC 4.4, I also did some internal cleanups.
For KDE SC 4.5 I want to completely concentrate on fine-tuning the code base of Dolphin, so that some long standing bugs can be fixed in a clean manner:
Information Panel
I totally underestimated the complexity of the Information Panel before KDE SC 4.0 had been released and was never happy with the code-base. I tried to fix things from release to release (which can also be seen visually when looking at the screenshots from the Dolphin-News). Now with KDE SC 4.4 the code-base is a lot better, although there is still some work until it can be moved to kdelibs to get shared with other applications (I blogged about it already in Information Panel and Tooltips). One issue that needs definitely to be solved for KDE SC 4.5 is a non-blocking fallback solution for showing meta information even when Nepomuk and Strigi indexing are turned off (bug 193592). Also fixing the missing meta information in the properties dialog (bug 190588) is a must.Column View
The column view has been added shortly before the feature freeze for KDE SC 4.0. I fell into the trap to assume that showing several columns cannot be much more difficult in comparison to the other views. The result was that the column view added a lot of complexity to the code and fixing column view related bugs was tricky. I cleaned up the code base for KDE SC 4.4 and am quite happy now: A lot of interfaces and workarounds could be removed, less code is needed and fixing column view bugs is straight forward. The beta releases and release candidates popped up some regressions, but they could be fixed quite fast.Location bar ("breadcrumb")
Long before KDE SC 4.0 had been released, the location bar was only meant as prototype. It happened too fast, that we moved it to kdelibs to make it available for the file dialog... It was my fault not taking care to cleanup up the public interface of this widget before KDE SC 4.0 (honestly speaking: There really where more serious problems to solve to that time ;-)). I could not manage to do a cleanup for KDE SC 4.4, but a refactored version is already available on trunk. There are two nice "side effects" of this cleanup:- Dolphin can now easily remember the expansion state of detail-view trees when going back in history (I've to thank Frank Reininghaus a lot for his contributions in this area).
- The Dolphin code could be simplified, as it is very easy now to remember history states.

The searching for Dolphin has already improved in KDE SC 4.4, but still needs a lot of work...
Things like these are what I'd like to fix in Dolphin for KDE SC 4.5, so please don't expect huge, new features :-)
BTW: I'm very happy to announce that on February the 1st I'll start working fulltime at Openismus. Most probably I'll get the chance to work with Qt for Maemo 6 (Harmattan).
