I'm personally a mobile player, and love to dress up my pets but its very difficult on mobile because if you try and acroll through your items in the menu to grab it and the item isnt something small like jewlery and is instead something like horse leg protectors or just in general items with a large width, it just picks the item up isntead of scrolling even if you tap the scroll bar itself, and i dont want to have to open a separate tab to search through my items just to have to put it in the search in the customization tab once i find it, and then do it all over again for each item.
It's an issue for customizing my stamps as well, i have to switch to the pc layout (smaller & harder to read) bcus to scroll through stamps you have to scroll below the box where you place your stamps and you cant drag them up, so its more inconvenient to try and customize if you are on mobile. (it also took me a while to find where to customize profile outside of switching layouts bcus the only ways I've found for changing stamps or even seeing profile is by going into owned pets and clicking in the memu above that(home < "username"< group name) or by clicking your username after making a post (im unsure if this is just me not noticing any option anywhere but i spent the first week i was on here confused on where to change it, and still am not 100% certain on if theres even a profile option like on the full site in the my stuff section and i tried searching again as i was writing this suggestion) and being on the full site is more difficult to work with as it shrinks everything down and skews layouts
Sorry for any grammar/spelling issues, and pls lmk if this has already been suggested or if I'm just missing something somewhere and somehow couldn't find the ways to make it easier on myself
Edit to add on: theres also an issue using the full site layout to decorate where for larger items like backgrounds if you accidentally move it wrong the screen scrolls off the pet to the side. so you have to let go of your screen to go back to the pet which is very inconvenient if you just meant to move something to the side and now you have to replace it entirely
