I love making parametric designs in FreeCAD. One challenge is to jump create aliases in spread sheet. Often while working in other workbenches, I decide to create new values with aliases. Then I open spreadsheet and I need to click a few times to get to alias setting (right click on cell, alias tab and select field). There is a short cut for alias setting: CTRL+SHIFT+A. However, for that I need to switch to Spreadsheet workbench, which also costs some clicks.
How about, we get an alias field right next to contents field (right above the spreadsheet cells and below the toolbars)? There is plenty of space there and 2 most important settings for cells are: content, unit and alias. The styles (colors, alignment and style) don't matter as much as the those. Units can be set by typing it with the numbers: eg: "2mm".
Would this help you as well?
Does it create problems for certain usage scenarios?
