Don & Doff Actionbars

[Ion Mage]

For EVA gear, the complexity of donning or doffing it is already reflected by the fact that you need to wear at least four different items (suit, helmet, airtank, mask), and if you want to do it optimally you need to manually fill said airtank to its max capacity if you want to maximize your EVA time.  Theres more than enough clicks involved here that the impression of it being complicated is already well conveyed IMO.  Adding progress bars to the existing process is just going to compound the waiting time even further, probably to a point not even the most sticklish among us want.
