I can answer a couple of your questions.
Another question which comes to mind is, if I were to create additional accounts with a separate wallet for each now while it's impossible to properly restore wallets containing multiple accounts, would it be possible to one day consolidate those accounts into a single wallet file once the backup restoration issue is resolved?
Yes, you can later consolidate your wallets by using the wallet_dump_private_key <account> and wallet_import_private key <private key> commands.
Lastly, should it be the case that this problem isn't a priority with the development team, is there a way to maybe vote for which to-do items get prioritized? I imagine I could post a bounty to get it completed by foo date if it's on the back burner, but if it's going to be fixed within a reasonable amount of time anyway, I'd rather save my BTSX/PTS.
I'd imagine the problem you mentioned earlier is a very high priority as a lot of people, me including
, have funds stuck in Bitsharesland that they can't access right now. I have faith they will be able to get it fixed soon, although I haven't tried restoring my wallet with the latest release yet.
In the meantime I think the community should focus on bringing awareness to the things you can do to prevent these things happening to you such as not using the same account on more than one computer, using more than one wallet on the same computer, or restoring your wallet with an old back up.
I think you bring up a good point about the community being able to vote on which bugs or improvements should be prioritized. I think it would be good to see everyone's opinion and where people are having the most problems, so that the developer's time can be focused towards the biggest issues.
