Steps to reproduce:
1)Have no Spidertron remotes in inventory
2)Click empty spot on quickbar, add Spidertron remote filter.
3)Greyed out remote appears on quickbar, with white as the selected color. (note this is the same color that appears in the crafting menu)
4)Open crafting menu, craft 1 Spidertron remote. Note new Spidertron remote in inventory has defaulted to black "unassigned" color, also note that Spidertron remote in quickbar has subscript 1 on it.
5) Click Spidertron remote on quickbar, note that the newly created remote in inventory is now in hand, despite the icon on the quickbar still using the icon from crafting menu.
6) Click on a Spidertron, note the color of the remote in hand (example purple) and in inventory has now changed to match purple Spidertron, but the icon on the quickbar has not (still white).
7) Release Spidertron remote.
8) Click taskbar icon for Spidertron remote, note the icon is still unchanged on quickbar, but remote in hand matches color of the synced Spidertron, purple.
9) Craft new Spidertron remote. Sync to different color Spidertron (example green). Take original Spidertron remote (purple) and put it in a chest.
10) Click taskbar icon for Spidertron remote. Note that the remote is now green, to match the only Spidertron remote in inventory.
11) Craft more remotes and sync to different Spidertrons. Clicking quickbar button always puts in hand the earliest sorted Spidertron Remote.
Last, but not least: The tooltip window in the crafting menu provides no details about how to control Spidertron. Thus, if you click on the quickbar, and add the remote, the only info you get is the ultra basic tooltip from the crafting menu. Even though you can click this button and get a remote in hand, the tooltip never changes, because it is filtering to the crafting menu remote.
This all came about because my friend, for reasons I can not explain, filtered a remote on their quickbar, and had no idea all the capabilities of what Spidertron could do. I kept saying, read the tool tip, it literally says all the cool stuff you can do with the remote. And she literally couldnt
