Thank you very much for your great software, Andrey. It is an impressive program.
I would like to request a couple of features, which are missing in version 0.89 (stable).
- show paper borders (e.g. with a blue dashed line similar to excel)
- Notes, which are only visible onscreen but not on the printouts

- make pictures resizeable
- possibility to make formulas bold and/or (double) underlined
- number/result formatting (x=12.345.678,9 or x=12.345,68*10^3 instead of x=1,235*10^7)
