•I think that would be a fair compromise if specific pieces of gear rememembered shaders which been applied to them before so player could choose from those he already equipped once for no additional price. Or at least there should be some kind of trial period during which you can revert changes and stay free of charge.

•option to see a full-body guardian with currently equipped shaders for every individual piece of gear while previewing new ones is a necessity. Right now you can't see the whole picture and often shaders that you think gonna be gorgeous with the rest of your set eventually don't add up to the look. Personally wasted a bunch of shaders this way.

•the idea of buying shaders you already got once for glimmer makes no sense at all. As a reasonable alternative though we probably could buy them for bright dust let say for 1.5 of a price for random selection of shaders we can buy right now at eververse. Another idea could be some kind of crafting system similar to what we have for weapon mods.
