I think you are working on v1.50 and we should wait for it. So I am waiting for that release. After that I will post a major suggestion for next version, but I have some minor suggestions useful for current release.
They are...
Single click for system tray icon. Drop box transparency option. Toolbars customizing option.Hope you will work hard again.
I will come back soon with new suggestions.
