I only want to see open bugs, not the resolved and closed, in the buglist

Filters on column already exist, but problem is that they are not persistent across sessions. So, you should set them again every time you logged in.

I suggested in another thread to create different tables for different type of tasks or maybe different status, in order to have a more intuitive and functional UI, but for the moment... no news about it. I hope could be considered in near future.
