I also think hard work should be rewarded (...)
+1 for paid upgrade of TM2.
I remember this kind of discussion was already there 3 months ago or so. But it's cool to so many of TM users that want to pay for something that's declared to be free. And I agree with JiHo that probably this would/could result with sooner and more stable release of TM2 and more development possibilities + some full-time side developers.
I would appreciate also some screenshots of dev version + some ideas behind written down, rather sort of explanation (we already know) that we found on TM blog. Indeed some short blog entries with some screen snapshots and dev notes would make it easier to wait for TM2 release, that's such a Holy Grail for us all now :)
Cheers,
