Yeah, we can discuss that at the sprint.

e.g. the current Kate application interfaces would make a good starting point, guess
needs to be just shrinked down.

Btw., does KDevelop support multiple main windows or is this then again a new process?

I was about thinking to go for Kate to the "each main window is an own process" scheme, too.
This would make the interfaces A LOT less complex, as each plugin would have only one view,
even the plugin/view split could be removed.
