Okay so you all know that there is kind of a shortcut to access to your inventory (by clicking " i " on your keyboard). Well i suggest that there would be one to access the shop. I know a lot of people (including me) who spend their time in the shop changing their outfit or to buying stuff.

By clicking "s" on your keyboard


You could easily & fast access to the shop

but s is used for ducking in wasd

Oh then Ctrl + S or something like that
