Smaller client solely for setting up shop?

Hello. Im still a noob in this game, and I know that this kind of suggestion is up to the devs in China etc etc, but just for the sake of suggesting an idea.

Lots of people use the catshops to sell, thereby leaving the client running on the pc for a long period of time, right?
The client takes up a lot of resources, so for those of us who use the comp for other heavy computing while the client might be running is probably inconvenienced by this fact.

I was wondering if there was a smaller client that will run with much less system resources and solely for setting up catshops, it will be so much more convenient. I mean we really don't need the huge client to be running while setting up shop since we're not doing anything else.

The graphics can be kept to minimal, just have to be able to know your location, where you are setting up the shop and set up what to sell/buy.
Keep the small client running behind other programs all day long and not be worried about system slowing down...

Just an idea. Since catshops are pretty big part of the game.
