I noticed something strange
when the image browser is docked to the main window of PL, you can easily check or uncheck multiple items of the filter dropdown menu.
however, when the image browser is undocked, the behavior is different. the filter dropdown menu closes after each check/uncheck action. this can be very anoying, if you have to check/uncheck a lot of items.
maybe you guys can look into that issue
i think filter schemes could also be a great step forward
