It would be useful if the Find Dialog had a “Search for whole words only” option.
It would be useful if the tabs (Messages, Search tabs) had a “Select all” option along with an associated shortcut (<ctr> a).
If a number of lines are selected then a right-click is performed, the selected items are no longer highlighted. The usual Windows behaviour is for the selected items to remain highlighted.
A MRU list for previous search items would be welcomed.
