Show FixInsight version number

I do not see a version of FixInsight I have installed, so every time I see an update available, I do not know if I already have the new version or not. It's a great tool, but every few weeks I go through the same routine of trying to remember if I have the last version or not. It ruins the good experience, unfortunately. A simple version number in title would be enough. Just a simple text, nothing more.
