So in Chaox and TheOddOne's streams, they were able to make their stores not have all the "hints" as to why you should buy each item for example showing Dorans Ring "Good Starting Item for Casters" and instead just having the ring itself which saves a lot of space and making it easier to just click on one thing.

I've tried searching around for info on it but I can't find anything.

Did they edit their game file to specifically have that or is there something in the game you can do to remove the text?

Can someone either link how to do it if it is editing, or maybe just give a response as to how to do it?

It sounds like they just changed the shop to the icon view. There's a set of small buttons right of the "All items" tabs that will switch it for you.
