Polygon Tool

I have tried every way I can think to undo a single step when drawing a polygon.  If you make a misstep there appears to be no choice but to start over which is a PITA in a complex shape.

So this is by way of an idea or a question.  How? If not, can we add that in please?  To be clear, I just want to undo the last step I made.

Also, this is a case where snap to grid or guidelines would be REALLY helpful if you are trying to draw a polygon that has sides at right angles to each other and to the screenshot.

Finally, a solution for people who wanted to be able to do irregular shaped highlighting.  Use the polygon tool, set the colour to say yellow, and dial down the opacity.  Works a treat

I agree some more improvement to the interaction would help here.  The undo last point is one i often run into and the other is the ability to easily do right angles.

The Undo last point is commonly handled using the backspace key, like in Photoshop or Affinity Designer/Photo

In general I think the pen tool in Affinity Designer is the best/easiest one I've seen, quite flexible and easy to start with for a new user.

One good solution for making things at right angles used in other applications is to hold the shift key, then the line drawn is constrained to the vertical, the horizontal or 45 degrees

I like both ideas (backspace to delete last segment and Shift to constrain to horizontal, vertical and 45°)  They are very intuitive.

I'd also add a further refinement.  When you complete the shape by returning to the start point, it would be nice for a proximity indicator to appear when you are in the zone where double clicking will connect you.  At the moment it's a little unclear, and you can end up drawing an unwanted segment.  Changing the cursor shape would suffice.

... and also... would it be possible to (say) hold Ctrl down to force the segment to be vertical or horizontal?
