Kind of mentioned already as a feature request by another HA user but I stumbled upon this one too recently.
I have an IKEA Idasen desk where the height is adjustable. In HA this height is based on a percentage instead of the actual height. I would love to see this changed into real height!
I don’t know if this also falls under low hanging fruit too, but I’ll throw it on the table: pre-defined heights. Variables you can set on which you can press a button so the desk aligns with the pre-defined height. This makes it soo much easier to set the height of a desk by just pressing a button.
