or maybe just a GUI option to rescan?
Yeah, that would a nice addition! Way easier to ask someone to click a rescan button somewhere, than to explain how to start up bitcoin with the -rescan switch.
Do you guys think it would be a good idea for the client to check if the wallet has been switched out, and if so, to do an automatic rescan?
Newer versions do this already.
Ah, my bad. Great to hear this has already been implemented! In which version has this been implemented?
