The first improvement they should work on is with the software itself, instead to work on features and alike.

I don't know about you guys but to me, the software is really hard to use. I don't mean how to use it because a kid can do it. But it takes all the memory of my OS. Up to the point, I can do anything else, not even keeping a browser open. I often need to shut down the machine or software and try again and again...

When I have a transaction to confirm, if I need to do it before tonight, better I start to try early in the morning! I can stay behind my screen all day long! I know, my specs are not huge (4+2 GB ram) but I believe it should be far enough. No idea what others use, I started to wonder if it could be better to run a VPS (considering you manage the security of the server efficiently or move your coins once finished)

I don't know what to say. Perhaps making a light version or something around. In a release not long ago, it was nicely improved but then in the next version, the problems start again. (usually the DAO synchronization)

By the way, with the mobile application, you only receive notifications right? You can't do anything else (i.e. confirm a TX)
