I'm using Cursor Enhancements mod, which lets me change tiers of belts using shift + mouse wheel. When holding a regular non Belt Draw belt the text for changing tiers will show for both that mod and this on top of each other. Think you could make it only change the Belt Draw tiers while actually holding the tool rather than on regular belts? That would fix the problem of double text.

When I put the Belt Draw tool on my hotbar, the belt tier will revert back to what it was when setting the hotkey, every time I've used it afterwards. For example: hotkeying the tool while in its yellow tier belt will keep the hotkey permanently as yellow tier despite me changing the tier. I've noticed using the tool directly from the toolbar instead of the hotbar will remember what tier it was set to recently.

Could use support for modded belts! Perhaps it would be possible to read the next_upgrade paths of the belts? Similar to what Cursor Enhancements "next item" hotkey does :)
