I wanted to know if there is any support in the tool where the user can select multiple unique labels and rename it as one label?

What I want is very similar to grouping thing which is available in the tool. But instead of selecting "n" number of labels and grouping them, I wanted to give those "n" number of selected labels a different label name.

Thanks in advance!! Please let me know if th

Also, "prev" button should not show if there is no previous sample

Like the "From this node to the previous node with a defined radius" mode, but interpolates radii for intermediate nodes by distance, just like how virtual nodes are drawn in the tracing overlay. When rapidly adding radii to existing skeletons, this would produce much smoother and more representative annotations.
