I agree that it's not necessary to have the AIO wallet as I used to use it a lot but a week ago the DB was corrupted and since then I now just use the online wallet to keep track of our mining transactions. The AIO does take up a lot of space as well so we just run the miner and that's it.
How do you JUST use the online wallet? Do you still use the official BURST wallet program, but just don't let the local wallet update? If that is the case - how do you stop local wallet from downloading blockchain?
Well I used to use the lex AIO wallet which has the local and web wallets in it but I now use the online wallet from here
Which ever one is up and running at the time I use them as sometimes one could be down for some reason.
