Closing gaps after deleting items from list

Hello. Love your shop plugin. Thank you. We've used it for 3 wipes now. My main question is, after I delete an item from the item list and update the shop, how can I remove the spaces where they once were and not have a blank space?

Also, second question, to add a new item that Facepunch releases, do you have an updated item list.

3rd question, my server is a 15x server with raidable bases. I have prices to buy and sell increased for them individually but would love a way to set a pricing multiplier to the general list as a whole vs item by item. Is there a way to do so? 

Attaching image showing the spaces I am referring to that I would like to remove so that it isn't obvious I deleted those items from the shop. There is not a line or space in the json and I've ran it through a formatter.

Hey

1. Make sure you remove items from oxide/data/Shop/Categories.json instead of Items.json
2. I don't but new items can be simple added into Items.json file 
3. Not an option currently but I was thinking about making something to help with setting up prices however its not easy to come up with solution which fits every server

Changed Status from Pending to Not a Bug

oh good to know about the categories edit instead of the list edit. Whoops. hahaha I appreciate your assistance. Off to do that now.
