Of course I'm making a content pack, and I'm in the texturing state for my first ever model. I think that it would be useful if there was a way to texture a model by hand. This would really help anybody. Also my second idea is to add a helicopter setting since they've been added. So yeah.
The editor had a few useful tools at one point, but I don't know why they were removed. Besides, you realize how many programs you could get that are way better than the toolbox for texturing? Just to name a few: Photoshop, Paint.net, Gimp, they are all excellent. I mean, sure, a bucket, eraser, text tool, and pencil WILL do the job, but seriously. Imagine what you could do with gradients, layers, more fonts, and tons of other things other programs provide. I doubt Manus has any plans to provide enough things to make the toolbox 2.0 worthwhile for textures since, well, it would take up so much time he could be spending making an amazing modelling program, which is the point of the Toolbox 2.0.
On Helicopters, I thought they were a thing in 1.0.11 but maybe I was wrong. However, I'm sure Manus will add it (if it isn't in), since he's got helis in his packs, as do lots of people. It'll be interesting to see what's done with helis and the toolbox.
I'll be thanked for killing a monster while you're burning in hell.
