Guys, before you even consider doing anything, just do those two little things which are really obvious:

- Make the GUI finally free of bugs
(Yes, there are still terrible bugs in the GUI - no errors show up but the UI often gets stuck and needs to be reloaded in the browser)

- Upgrade the website to make it look like you actually want a new user to try out your product
(Yes, when you sell some software it's usually a good idea to show a screen-shot)
