In variants with both menuglyphs and object materials, the glyph shown in the menu should match the object’s material.

This could be done relatively easily with a hacky solution in ASCII windowports, but a proper implementation for tiles-based windowports would be challenging since it amounts to adding new tiles for every object-material combination.

The Amulet of Yendor (and fakes) should have some bright, noticeable color that is not the same as the metal color used by every other amulet type.

An option to disable Japanese item naming.

All eggs display their size, which is the same as their monster size (so e.g. an unidentified killer bee egg would be “tiny egg”). Non-monster eggs are small. Could also change the egg weight to match.

The hero should be able to see from the get-go that the Candelabrum has seven candle holders, so display it as “(x/7 candles attached)” instead of just “(x candles attached)”.

Whether an artifact has or hasn’t yet cooled down is visible to the player.

Interface option to shorten “blessed”, “uncursed” and “cursed” to three letters so that you get more use out of the inventory sidebar.
