Locking zoom view in light table (feature wish)
Here's a little feature wish, based on something that is somewhat already implemented, but undocumented and a little bit ackward, that I just found out and that I find quite useful for culling/inspecting photos:
Pressing Z brings the zoom view of the picture, but as soon as the Z key is released, it comes back to normal view. This is the documented feature. See here: https://darktable.gitlab.io/doc/en/lighttable_chapter.html#lighttable_overview
Now, I just found out that when in zoom view (so while pressing the Z key), if I manage to apply a keyword/tag (with ctrl+t), it will permanently lock the zoom view, without the need to maintain the Z key pressed. It seems to only work with ctrl+t, so it doesn't work with applying stars or color labels. That's the undocumented (and maybe unplanned?) feature. To come back to the regular (unzoomed) view, I just have to press Z again.
My wish/suggestion: to have a real (and less ackward) way of locking the zoom, like a key combo (could be shift+z, since ctrl+z is already assigned to the sharp regions/focus view).
