In theory it should be possible, and I’ll be researching and trying to implement it after the coins wallet are implemented functioning and well.
I prefer MAID, or BTC, but if anyone decided to send some other altcoins compatible with Omni I will certainly value it too.
There will be filters in the top bar, so you can search quicker. Now, you can see each card has a color according to its type, this will become also an option for the user, i.e. when you create an item you can assign a color to it. So you can think of something very similar to the gmail labels, and one of the filters could be “by color”, and this is how I’m seeing folders can be implemented without breaking the simplicity of the UX.
Yes, I started working on a prototype for this. The plan is to begin supporting SAFEnet altcoins/testcoins (and safecoin of course), so you could create wallets for different SAFEnet coins and make transfers either among them or to other people’s wallet.
As part of this effort I’m planing to propose (by demonstrating it with a basic implementation) the use of SAFE vCards as the way to share your public key/s for receiving coins. As mentioned earlier, eventually I’d like to also have non-SAFEnet coins supported but that’s a longer term plan.
I just found out that the use of vCards was earlier proposed by @Tim87, and it’s related to what I proposed here, so perhaps having a real implementation can help us decide if this can be the standard way in SAFEnet, which is also related to some other discussions about defining the standards for SAFEnet.
