I've gone over our long-term roadmap and revised our list of milestones based on where it appears folks want to go.

M2 - I'm relabeling our current focus from 'features' to 'Interface Redesign' since between Mental and Bulia's efforts, this has been the lion's share of the effort.
M3 - Since there wasn't any issues raised to my proposal to make the next release focus on the C++ and codebase cleanup work, I've formalized that as our next priority. As well, I've tentatively listed the layer dialog as the Gtkmmification objective.
M4 - For milestone 4, I'm taking the suggestion of focusing on doing a bug hunt, as it really sounds like we need it. Of course, this doesn't mean we should put off bug fixing until this milestone, but rather at this point we should each set aside our feature implementation efforts in favor of focusing on clearing the bug queue. I think by tag-teaming the bugs all together, it'll be much more enjoyable than just tackling them as they sufficiently annoy us. ;-)
Additionally for M4 I've committed us to doing a codebase-wide implementation of Mental's new unit testing framework. Doing it at M4 should give us enough time to get that framework well-tested. I figure doing this in parallel with the bug hunt will be synergistic and will readily leverage each other's work.
M5 - Gtkmmification
M6 - Plugin System
M7 - New features. I figure with the new plugin system fresh out of the shop, focusing on implementing features will give it a good road test.
M8 - STLification.
M9 - Extract SVG Canvas.
