2D Plan Suggestions

There are 2 things I am desperate for in the 2D plan.

Firstly, an undo button in edit mode (why it doesn’t have one I don’t know).

Secondly, when you place a bunch of fixtures and then place a bunch of other fixtures into the 2D plan can you please set it so that once you place a new set of items in the plan that it deselects the previous items that were placed? It’s absolutely maddening when I’m banging together a plan and forget to select so when I start aligning things it aligns all the previous additions as well.
