For the purpose of making handling of (not so small number of) KWin bugreports simpler, each bugreport should have a priority assigned, making it possible to sort the list of bugreports and see what bugreports should be handled first. For consistent setting of priorities, these rules should be followed:
There are 5 priorities, VHI (highest), HI, NOR, LO, VLO:
A short simple way of explaining the priorities is "VHI ASAP, HI reasonably soon, LO somewhen, VLO who knows when".
It is important to note that these rules are just guidelines and do not need to be strictly followed when it makes sense (for example, a minor crash that should be however simple to fix can get HI in order to be checked before next release). Specifically, the examples given are just examples and the description of the priority should be used. The main purpose of these rules is to help with handling many bugreports, not to have rules for the sake of having rules. It is not a big problem if at the time of a KDE release there are tens of HI bugreports.
Wishes should use the same priorities like normal bugreports.
