Just wanted to drop you all a line about MissionControl. Most of the issues at this point are related to 3rd party extensions. In MC I have tried to update the layouts that come out of Joomla with more usable HTML. To do this cleanly I used phpQuery to perform some DOM manipulations on the output. This worked out pretty well for the built-in extensions, but it's much more troublesome in 3rd party extensions. The problem is that 3rd party developers only ever develop their extensions against the default Joomla admin templates: Khepri and Bluestork (which are essentially very similar). This means that I have to debug and fix every aspect of these extensions against MC, and that's just not practical.
My plan going forward is to work on a new version of MC that basically doesn't transform the output of the extensions area to such a degree as it does now. It won't look quite as good, but I think i can keep it pretty simple and make it look decent for most extensions. Also I plan on limiting the use of phpQuery to some specific things, such as the tab view for content editing. This should also speed things up a little bit.
Also i'm going to stop developing for Joomla 1.5. The current version will be the end of the road for that release so I can focus on the new 1.7+ version.
If i'm not very timely in answering posts in this forum, it's because i'm now focusing on this new approach. Please bare with me and i'll give you a status update as soon as I have some more information to share.
