hi,
seeing that the latest update features some improvement for tabs I'd like to suggest adding some widely used hotkeys by default:
ctrl + t new tab
ctrl + w close tab
i use these hotkeys all the time in firefox so it would be natural for me to have the same keys in musicbee.
as ctrl + t is currently set to the album tagger by default i suggest changing that to ctrl + shift + t (analogous to 'send to -> converter / volume analysis')
