True, the Maliit situation is known to need improvement. The input goal proposal mentions this specifically, it's one of the things that (as elected goal champion and developer) I want to tackle personally.

Unless another motivated developer shows up first, of course - we're happy to distribute the workload among contributors and provide mentorship where necessary, so the ambitious proposal has a chance at all of its items getting tackled within the next two years. Follow the link to the goal proposal and find our Matrix room at the bottom to join the effort :)
