foundry-filepicker-favorites VS macros

the module filepicker improvements can let you add some pre definited folders to the folder tab on the file picker so you can easily set where to upload with a single click

Moulinette (specifically Moulinette Core + probably Moulinette Scanes, Tiles, and Image Search given what you mention). It provides an experience more similar to what you're describing to look for assets. I'm too finicky about my file compression to personally use it much - I'm a Filepicker Improvements stan myself as its ability to favorites to the filepicker suites me well - but a lot of folks love Moulinette for the experience you're after.

I'm personally a Filepicker Improvements fan, but a lot of people love bigger overhauls like Moulinette's search options or Alpha Suit's file manager. There's also folks that prefer just working from their own files/internet and go Drag Upload.

Filepicker Improvements - Lets you favorite folders for quick access when selecting token images.

Filepicker Improvements

Yeah, learning how to do other stuff in Javascript is a good way to start. But then maybe look at things like the example scripts in the community macros: https://github.com/foundry-vtt-community/macros

Have a look at the community free macro module. https://github.com/foundry-vtt-community/macros

If you code at all, then Foundry jumps even higher up the recommendation list since it's designed intentionally to allow people to build stuff and add functionality. As someone who used to mess with R20 macros and their proprietary API, this is probably one of my favorite benefits to Foundry. They have some typical documentation though if you prefer examples the community macros repo is great for that.

Read some of the shorter/simpler macros from https://github.com/foundry-vtt-community/macros to get a sense of how they work.

This macro in the FoundryVTT Community Macros GitHub repository "selects all actors of the same name on the scene." I haven't tested it, but these macros have never given me issues in the past, and I recommend checking out that repo if there's ever something you're looking for.

Quick size control (#2) is generally handled by macros. There's a macro for quickly swapping tokens between 1x1 and 2x2 in the community macros. If you want some that will just bump a token up or down 1 grid size, I can get you mine personal ones in a bit when I'm at my main computer/
