Hey K1lly0u, if you are not busy, could u please add submenu for commands page? Items has got sub-menu because u can get item categories easily.
Submenu (categories) for commands could take your time but, could u please do it? I have got 20+ commands and i need categories for players to find things easily. 
+ when we change the order of commands in json, it should be listed like that.
Right now it is alphabetical and it is not a good way to list commands. We  should be able to order them like;
We need this:

"order": "1" - "submenu": "menu1",
"commands": {
  "something": {
    "description": "description",
    "iconName": ".png",
    "order": "1"
    "submenu": "menu1",
    "commands": [
      "consolecommand.command"
    ],
    "displayName": "name",
    "cost": 500,
    "cooldown": 600
  },​

@tanki what do u mean? Solved sorry? 

I've edited my post, i can't delete my answer....  but it solved for me ^^

What is solved? I asked for an update. This is not an error. Did u already add sub-menu to commands category? 

My problem (related to your 20 command) but its fine now.

No, i'm not a developper, sorry but it's a great suggestion

Yea thanks. I guess it is something hard to do. K1lly0u is updating other plugins but he don't update this one until there is a critical bug.
