I may be missing something obvious. Is there a reason why the transformation palette is missing “coordinate shift” (move X, move Y)? Going through Path/Transformations just to shift by a specific amount, seems like a longer step.
You’re not missing anything, no. What do you need this for? I find myself needing exact coordinates translation exceedingly rarely.
You can use Path menu > Transformations.
I work with non-interpolating multiple masters, where I often need to apply the same transformation across multiple glyphs or their parts. Scaling, rotation and skew are ready to go from the palette, but the basic “shift“ is missing.
I see. I would suggest adding a keyboard shortcut for that, then. There are some functions I use a lot (depending on the project) that aren’t at the forefront of the UI. I set a keyboard shortcut and usually find myself not needing it anymore after that project.
