I really like many of the useful added features. There is a lack of useless bloated features that frequently plauge other developments.
1) "Put tab in new folder" feature. Simply brilliant! Even the implementation is very neat. You easily pack multiple tabs into one group. No dragging into position nothing. Very useful to quickly organise the tree. Especially with multiple selection.
2) "Hibernate tab". Quick reduction of memory usage.
3) "Highlight" tab feature. Neat way to make it stand out.
