Currently, TC, when using QuickSearch filter, displays an icon on the lower part of the panel. Although, this indication is there, is easily "ignored".
I proposed a couple of settings to wincmd to enhance the visual indication for both depicted features:
BranchViewBackground=#FFFFFF
QuickSearchFilterBackground=#080808
I think this is a good way to state the status of a panel.
Background color based on branch view/quick search filter
