This page is meant to collect various planned features/enhancements. For the release planning all features that you want to implement should be listed in http://techbase.kde.org/Schedules/KDE4/4.13_Feature_Plan (you can for instance just link here).
Note that this page is strictly for developers, and NOT a wishlist.
This section is for features where you have concrete plans for implementation (doesn't have to be in the next release). A short description, the approximate timeline if you know already (e.g. for version X), and the reason why the feature is needed would be interesting.
I plan to replace the kolab proxy with a new resource that derives from the imap resource (so no additional agent anymore). Each imap resource would have two root collections, one for email and one for groupware data.
The primary reason is to reduce the overall complexity of the design, I expect the new resource to be easier to debug (because it's mostly the same codebase as the imap resource) and to be less error prone (because it's one less level of indirection). Other reasons are:
List in this section ideas that you think should be implemented, but you currently have no plans of working on in the near future. It will hopefully allow us to share some of the ideas that are currently only existing in one or the other head.
