Thanks xeroc for your answers. I've got a few more questions/observations from these,if you have the time:
I believe the GUI should a) give the user the option of titan vs non-titan, and b) have a very clear, per-account visual indicator of whether the account is TITAN-enabled or not. The documentation scattered around in the wiki is tricky on this aspect, and
http://wiki.bitshares.org/index.php/TITAN#GUI_Mode is very unclear about the fact that the account, when created from the gui, is
not TITAN-enabled.
As for deleting accounts, come on now. This strikes me a bit like treating users like children. Hide it behind an advanced mode and a confirmation dialog, sure, or ask for the password to confirm the operation, but it ought to be possible.
What would be the most straighforward way of moving accounts between wallets now? I mistakenly created 3 extra accounts when starting out, and they do little else but clutter the display. I believe this procedure essentially boils down to exporting the private key for each account and then importing on the new wallet.. but I couldn't find any howto.
Are there any special considerations to have with TITAN at all? Would I need to back-up the wallet after receiving funds with TITAN accounts?
