[This site] Improve the bug tracker please

Hello,

you build a very simple bug tracker here. If you worked with others you feel not so comfortable with this article like system here (my opinion).

I'm missing some core features of a bug tracker like:

• Choosing the software version from a dropdown (at the moment you have to add a [4.0.MYVERSION] before the title)
• Let the customers see, in which version the bug will be or is fixed
• Add the status assigned or in work or something like this to bugs. So everyone can see if someone is working on it (or not)
• Add importance level like low, high or critical (or other words you like)
• Let all options be able to filtered (so I can see which bug from version 4.0.8 are critical and not fixed as an example) - show us how powerful IP.Pages can be with this!
