As I said I am going to update to version 4.do you think it is better to use your feature for this
choice on current version (version3) or it is better to use this feature after updating to version
4 ?
I'm not sure what you're asking exactly. The feature doesn't exist in either version yet. I suppose if you're hoping someone will develop a mod for you then it's probably better to wait and ask for it for vb4 to avoid needing changes to it (although something like that probably wouldn't require a lot of changes).
It would probably be better to post a request in the "Modification Requests/Questions (Unpaid)" forum if you're requesting that someone develop it for you.
