sandbox is slow…I know not why. and very crashy.
Nevertheless it needs the option of 2 separate proteins…..or symmetry at least. then it would be a real sandbox where we can try out ideas more relevant to the puzzles being set 2day. the option to have additional filters oft used these days would also help.
If this is a sandbox….then Foldit needs to open up the opportunities….give us a chance to concentrate on areas of the game that we are weak at and want to improve.
just my view as a returner
