Now the official forum can move on to pestering poor Christian about what should be in v8.
Except for "file collections" (a la DOpus), I can't imagine what I would want to add! Especially now that TC has directory breadcrumbs and the optional as-you-type filtering of the file list.
So I'm a hopeless fanboy, but TC is that rare kind of program whose author seems to always be a step ahead from me in his designs. Usually you wish for a feature, request it and maybe see it implemented in a later version. With TC it's been the opposite: when I thought it needed a particular feature, I looked and most of the time it was already there.
Minor wishes, maybe. Here's a great concept that TC might steal from DOpus: as-you -type selection with the colon key: The : key opens the Lister Search field in selection mode. In this mode, all files and folders that contain the entered search string are selected. For example, to quickly select all text files, press :.txt and then return. To cancel the selection press escape.
