you will love 0.0.73 :)
1) was fixed, definitely!
2) is new to me, I never tried to reset more than once :D
3) yeah dasius said that this is a veeeery minor change
4) this was fixed in #73
5) yeah this has been fixed somewhat around #72 - my way of fixing it once for all was:
* enter game, fix graphics settings
* ender sandbox, fix graphics settings
* enter shop mode, fix graphics settings
Since then everything was settled :)
