I have a suggestion for you to add to the wallet.
You mention in the PDF to do backups as often as every day. How about adding a routine to the wallet so that every time the wallet is opened, it updates (which is normal), then backs up the wallet and blockchain when it's done. Then, when the user's wallet or pc crashes, it gives them the option to revert to backup (copy the backup files and restart the app to let it update from last backup), or they can wait to download the entire blockchain and start over which takes hours (and eventually will take days).
That would be a plus, if gun could users could pretty much guarantee no coin loss, and no super long recovery on a computer crash.
Interesting idea and maybe not that hard to do. I have started a list of potential upgrades and will add that one for sure.
The backup part is easy, add a line to run a backup script on completing the update, the script can run in the background once the check is done.
The recovery part is a little more difficult, you have to check the integrity of the current data and 2 versions of the backup data (in case the wallet crashes while backing up, it reverts to the previous backup) before recovering.
The toughest part, is not bloating the backups.. If you time/date the filename there will be no issues with telling which is which and loading the latest un-corrupted backup, but deleting old backups so that they don't bloat the folder is another story. That takes logistics, and a lot of programmers aren't into it.
The reason I suggest this, is that the PC my wallet is on is my daily driver pc. Shit happens and it crashes enough (every week or so enough cat hair gets in the way of the cooling vents), that I back the folder up regularly so that it's not an issue. But, from my near 20 years experience doing tech support for my friends and family, most people that aren't computer savvy enough to backup manually and will turn away because it takes hours to reload.
Plug and play, is what keeps people using something. As soon as it gets complicated it turns some off, and the more complicated the more it turns away.
