Hi Marcus,
thank you for considering a donation.
I think it's normal for a version 0.9.5 to be buggy.
I also consider it normal for a version 0.9.9 to be (almost?) bug free - I have already bought software with high version numbers and a long history, but still lots of bugs although I have spent a lot on it...
I know I cannot provide answers to all questions - that's why I started this forum early in the development.
If there were 20 people barking up the same tree as you did, what you were asking for would have been implemented already.
To be honest, I expected more feedback from users both here in the forum and on the donations page
People are downloading the program like mad these days - maybe this will change in the future...
