Guys from JetBrains - you are doing amazing work. I'm big fan of MPS for over a year, but only now I have the possibility to work on actual projects using MPS. Sometimes it's like a miracle, sometimes it's a curse.
Unfortunately, every single day I encounter new bugs in MPS. On average - 3 bugs per day. Really, no kidding. 12 issues filed in your tracker since 10th of October, and that's not every issue I faced. Usually I give up on bug reporting after spending more than an hour per day.
Please, guys, do a release concentrated on bug fixing only. It's so much pain to see that this wonderful product is overwhelmed with bugs.
MPS already has very steep learning curve, we need to make it easier for newcomers, not harder.
