It feels like the most common workflow is pressing that button in the top right to open the label list, opening the dropdown, and selecting a label. I think this could be optimized.

One idea: Bind the label list menu to a key like spacebar. Replace the dropdown menu with a list of labels which are already clickable, no need to open the dropdown. This would change the workflow of selecting a label from 3 clicks to 1 click.

Hi neckardt, Thanks for your suggestions! I will consider it in future optimized!

When corner-point rectangle selection is enabled, the cursor should be pointed to at all times by one horizontal and one vertical line (a big cross that extends to the ends of the window). Otherwise, how do I know whether I got the entire image in when clicking somewhere to create the first point?

Hi StavrosK, Thanks for your suggestion. I will merge this feature to main soon. After rectangle created, you can drag the corner or edge to adjust it

Oh, I didn't catch that, thanks! Maybe add "drag" markers, if you don't already have them?

There is already exist a mechanism for handling mouse press event. When mouse press on the picture, it will determine whether any polygon is pointed first. If pointed any point of polygon, it will modify the polygon. If no point of polygon is pointed, it will determine whether corner or edge of rectangle is pointed and modify it. If there is no polygon, edge or corner of rectangle pointed, but pointed inside the rectangle, it will move the rectangle. Otherwise, it will create a new rectangle
