After editing a material or adding textures to create my own it would be great to save the material for reuse in other projects.

As a graphic designer and illustrator wanting to create mostly mockups of books, picture books and magazines it would be extremely helpful to have more models (all of them have to many pages for picture books) and more paper-like materials to choose from. I haven't found a slightly rough paper structure (cardboard paper is too rough, glossy paper is too glossy) yet, yet this is a material that I'd probably use all the time.

How can i sell my own OBJ's on Adobe Stock for people to use?

It would be great if each product came with a template so you can open it in illustrator and create designs that fit the dimensions exactly!

Vehicles: Would be fantastic if you could make car models available for vehicle wraps. Or at least the option to import blueprints/renderings of them.

Pre-made Car Assets for Car identity and design.

I think this would be great for tradeshow booth mockups. If there were stall and booth kits in here I'd be using them right now to prep for CES.

Providing a mannequin-like 3D model for placement of people/dummies or for work in fashion design

3d text

add a "find similar" button or option to models, testures etc. and have it link to adobe stock to make it quicker to find assets for substitution

3D Models of point of purchase (POP) display assets. Different styles of basic product displays like floor-to-ceiling or counter-top product displays.

In C4D there are infographic presets ( Adjustable piechart etc.) that are very useful for some people. That might be an idea for later.

but I don't see how you can actually size the model to the exact size you want. For example, a 6in x 8in pouch. I would like to choose a pouch and have a window for the width and height. I can then decide how "full" I want the pouch to appear.

Dropper bottle models

Some help assets that don't require blowing a lot of time watching videos. I'd love to just search for what I'm after.
