Allow setting cell padding
I would like to see the ability to set the inside padding for all cells. Especially with wrapping text, I want some extra spacing between the text in adjacent cells to improve its readability. Currently I add blank columns/rows to add the spacing, but this makes navigation worse.
E.g., for headers I want extra top and bottom padding, and for data cells something like 3pt left and 12pt right padding would give enough margin to keep text visually separate between lines.
There is already an indent option, but this allows only changing one side, and thus is not able to layout cells properly. I suggest to keep that, and add left/right/top/bottom padding as an additional formatting option in Format|Cells -> Alignment
