• Spawn armour stands with clothing from command blocks. (Jumpscares.)
• Spawn and pose armour stands with traits such as: Pose, Arms, No Baseplate, Invisible etc. 
• Edit existing armour stands with /entitydata (As shown in the video.)

Alright, these requests sound quite feasible.

Also, can I have a breif explaination of why you cannot add No AI mobs?

 Regular mobs are a pretty big resource hog on any creative server. If they don't have an AI however, they shouldn't be too much trouble. Do you happen to know if mobs without AI can still be pushed around? If they can be pushed outside of your plot, it gets significantly harder to limit the amount of mobs per plot.

Thank you Pat! No AI mobs cannot be pushed around or interacted with in any way. You walk through them like signs and tall grass. They are for decoration mostly.

I'm working on a few different ways to allow players to edit existing armor stands as well as command blocks that are supposed to summon them. One of them is to use this fancy book where all the different values and their meanings are described.

I'm also considering creating a command similar to /entitydata (that takes plot protection into account), but since the parameters will look slightly different from the vanilla command it might just make things more confusing.

Thanks, Pat. I hope this goes well.

/entitydata has been added. The only current feature is spawning a book which can edit armor stand data, but there are more features planned. I also took the liberty to fix armor stand protection which PlotMe has refused to do for quite some time.

Thanks! It works great. Can you add armour stand invisibility?

I'll consider it, but I'd have to add a limit for amount of entities per plot first so that someone doesn't spawn a thousand invisible armor stands and we have no idea what's causing the lag. :P

it would be quiet simple since mobs are disabled

I don't know if this will help but you can see all invisible armour stands in GM3.

Ah, I had no idea you could do that. That's a nice feature, I'm sure it'll come in handy.

I'm currently finishing up the entity limiter and will add it as well as invisible armor stands in a few minutes.
