The option to click between cells to add a new cell make inputs hard to use

[LaoTzunami]

Describe the bug I keep on accidentally adding new cells when trying to use single row input cells.

To Reproduce Steps to reproduce the behavior:

1. Go to any notebook that has single row inputs that control other cells.
2. Try to click the input fields with your big thumbs on a smart phone or quickly with a mouse when you are distracted presenting it to other people.
3. When you inevitably add a new cell by accident instead of what you were trying to do, quickly try to close the UI while apologizing to the audience.

Expected behavior It was much better when you added a cell by clicking on the + icons on the left. Please do not add cells by clicking between existing cells. If you guys must have that option, please shrink the area between cells that adds a new cell so it is harder to click by accident.

Example This is the notebook I was trying to present, but most notebooks use this kind of setup: https://observablehq.com/d/525efdbf20cbb541

Thanks for the feedback and colorful reproduction steps. I can imagine your frustration while presenting; I and others shared your experience. We’ve reverted to the older add cell menu, including removing the blue bar you describe that let you click anywhere between cells to add a cell.
