1) When I went to create a polygon and put down a few points, I wasn't sure how to finish dropping points. I tried a few different strategies, and ended up accidentally deleting the polygon, before I found out the correct way to do it. First attempt was clicking on the black part of the top toolbar, but this did nothing. Second attempt was clicking on the mouse pointer tool, but that cleared the input. Third attempt was right clicking, but that cleared the polygon tool. Now I'm not someone who typically uses keyboard shortcuts when first using a product, so pressing "Enter" was the last thought on my mind. Before I tried "Enter" I made the mistake of pressing "Esc": shoot, another cancelled polygon.
Note that when using Figma, they provide a "Done" button while using the SVG tool. This was a bit of a frustrating experience to not only be stuck without a polygon on the page, but the app ended up deleting my work upto that point.
If someone was using this tool to draw something intricate and made a slip of their hand near the end, oof, that would make me want to rage-quit computers for the day.
2) Also, there was not undo functionality. It would be nice if I made a mistake and could press ctrl-z or press an undo button to get back into using the polygon tool with the previously placed dots put back in their correct spot
3) I think it's confusing a polygon isn't added to the features column as soon as you put down the first node.
This has some strange side-effects: one is I can click on other features, edit their properties, but still be in the polygon editing mode for the polygon which hasn't been added to the features yet. Another is I can click around and edit features, but when my mouse goes back to the map, it's still in polygon editing mode.
Again, I love this product concept and will keep a look out for updates. It has a slick looking UI and is a really cool concept. Good luck!
