I've managed to lose a load of engineered modules thanks to the "Sell old module" button. In its default appearance it has a switch icon next to it, with the switch in the left hand position. As anyone who has used an Android or iPhone in the last 10 years knows, left = off = this feature is disabled. Great I can now reconfigure my ship really quickly and store all the modules by default.
Nope, when you click that button to turn the feature on the switch moves to the right and the text changes to "Store old module" and then you realise you've been selling all your stuff without realising. I rarely sell old modules, so have lost a ton of engineered modules. Thanks for that. (Would really appreciate them back, some of them were G5).

A nice improvement in the livery section, would be to have a HUD colour selector UI. As I'm sure you're aware plenty of users modify GraphicsConfigurationOverride.xml to change the colour of their ship HUD. How about bringing this in-game, and even better make it a per-ship setting. The orange HUD looks great in a Ferdy, but completely out of place in a Cutter, where a blue&purple theme looks much better. We already have a UI brightness setting, so why not colour? You could put different defaults on different ships so there's more differentiation.
(It'd also be awesome if these UI filters didn't apply to images in the UI, such as codex or people's faces)

In the shipyard screen, bring back the ability to see the full loadout, also it'd be nice if the ship thumbnails matched the actual ship paintjobs.

If you're going to have a horizontal scrolling UI, actually take into account the user's aspect ratio or let us control the width. Long gone are the days when users only play on 16:9 monitors, some of us have 21:9 or 32:9. VR Users may prefer to look left and right rather than scroll, or they may not.
