Valentina 2.0. -- What is your 3 DREAM features?

[Erich Geiersberger]

- Cross platform language support (already discussed here)

- Sub-selects on cursors (already discussed)

- Callbacks for client timeouts on active cursors
It would save a lot of error tracking if we could get a message in that case.

- Better documentation
I know it's not easy during development, but I would love to have a 
complete list of error codes including system errors.
