Bug tracking software?

[Stevil]

Hi Tony, Dan and team,

I'm wondering if there is such thing like a list of known bugs or something like a bug tracking database or excel sheet?
Right now it is difficult to know whether a bug has been already submitted or not.

For example: In my old company they used mantisBT for that purpose but I think there will be a lot of tools available.
Sorry also if I did not see any old thread related to this before opening a new thread.

Best regards
Stephan
