With the addition of the 'universal' aesthetics in apex (trackers, holo-sprays, banners, etc.) and the long standing vitality of Apex Legends it's becoming increasingly harder to navigate through all available outfitted selections. My suggestion is a 'Sort by' menu of sorts. You could go by color or season or event. My suggestion is really driven by how long and awkward the gun charms and banner decoration menus are. Scroll, click to view, click the next option and so on. It would also be helpful if when the cursor is hovering over an option, that it be displayed (but not equipped) as a preview rather than clicking every single option.
On a similar topic, I am heavily suggesting- if not begging, that 'loadouts' / 'glamour plates' be added. To have a saved banner set up and saved for use at a later date. I would typically rock one specific banner set up on Loba, but if I am playing with friends and we want to match skins my banner no longer matches. On Loba, I have about 3 main banners I will switch between but this means I am rebuilding my banner every time, either from memory or the short photo album I have on my phone.
Continuing on the topic of item clutter, I think any new unlocked items should be at the top of the menu when I open it. If I have just gotten a new weapon charm and I didn't view it upon the initial rewards page, when I select any weapon and enter the 'Charms' tab, there is no reason for me to be scrolling the entire length of the page to find it. Especially bc the red notification marker can be easy to miss after scrolling so often.
