If it is possible I would like a way of seeing if a speedloader has bullets in while it is in my inventory without having to put it on my hotbar and selecting it.

Yeah, will do.
Should be in the tooltip tbh.

I'll look into it.

Question: will it show:

• whether there are any bullets in it
• whether it is full or if there is empty space / spent bullets
• which bullets are in it

or some combination of the above? Or will that be a config option?

How's this then? =P

@PrincessRTFM It looks like its from actually addons, it gives you the Code name, OreDict name, metadata and the Unloacalised meta name

Holy shit, I didn't know it was even possible to do graphical renders in tooltips. As a coder, I really want to know how you're doing that; as a player, I just want to know what the control for advanced info thing is about.

It is indeed Actually Additions. It shows up when you have advanced tooltips enabled (F3+H).

The way that render is done is pretty simple: There is a Tooltip Rendering Event. I hook into it. I know my revolver GUI is 74px high, I render at half scale, so 37, and each line in a tooltip is 10px, so if I add 4 blank lines (or in this case, containing some placeholder text), I can find those later on in the render event and just draw on top of them.

right, this is a thing for next release.
