I’m using the interactive labeling editor frequently and realised that it would really make things much easier if there would be a faster way to select labels in the “current label” list. A very common use-case is the merging of two (or more) over-segmented labels.
So far you first have to look up the label ID of one of the two labels you want to merge in the image then go to the “Current label” list on the right to find and select this label (which takes quite some time in case you have many labels). Then you can go back to the image delete the label you don’t want to keep by right mouse click and adding the selected label from the list by left mouse click.
It would speed up the whole process a lot if one could instead of manually scrolling through the list to find and select your label of interest do the same directly in the image. Left or right mouse click wouldn’t work here of course because that assign or removes labels but I was thinking of a hotkey that would automatically select the label from the “Current label” list that the cursor is currently pointing at in the image. Maybe there is already such an option and I’m just not aware of it but if not it’s probably not too difficult to add it.
