Thanks. But there seems to be a problem. It takes far too long to select the tracks especially when there's a lot of them. For example when clicking on an artist header that contains 135 files/1.8 GB it takes around 15s to complete the task. During that time musicbee is unusable. Anything that can be done to improve speed? My pc is fairly old but this does not seem normal at all. I use this function a lot now and I'd be really glad if you could somehow improve the speed.
