It might even be possible to show trivial information such as filesize in a tooltip, without having to open the right-click menu. Anything else should probably not be done automatically though, as it can be potentially a very slow operation to first fully load the instrument and then show its sample properties.

Initially, I wanted the size to be shown near the file in a column. But it takes the place on the screen, and it and so is not enough. Now I understand that also time for a miscalculation of all tools will be spent...
I will be grateful if you make file size as described!
