When you want to remove supports you can select multiple supports. But if you change mind and you haven't still clicked the delete button it is hard to unselect all manually, so a button to Unselect all the supports would be useful.
Thanks.
Hi, thank you for your advice.
Currently, in v1.8.1, you can simply click any other modes (e.g. Add, Edit) to unselect all supports that were already selected under delete mode.
But we will certainly consider your suggestion, maybe the ESC key will be used to unselect all supports in the next version.
