macros VS itemcollection

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/

Try this one: https://github.com/foundry-vtt-community/macros/blob/4e25a66ef7990dbcb0c9015b554286de147c5116/actor/5e_lay_on_hands.js

For DND5e, there's a couple options. Item Containers and Inventory+. Both work on v9, neither have been updated for v10. I believe Item Containers will work on it, but Inventory+ won't. Inventory+ has a new repo for v10 that hasn't started work yet if you want to track that. (I do, it's the better option for me.)

Inventory+ and Item collections seem to be the only two choices currently available, and while both could be worked into a useable form, neither plays nice with the tidy5e sheets that I've come to know and love.

Item Collection

you can use the module Item Collection to create containers in your players sheet, it adds also configuration to the container item about how to handle its capacity, max weight, actual item weight (for bags of holding and such where the contained items weight zero) and so on.

This is what you are after - create all type of containers and bags. You can set the fixed weight and anything you put in it wont change the overall weight on your character. Its great. https://foundryvtt.com/packages/itemcollection

I believe the Item Collection module may be what you're looking for. Make sure to check out the GitHubfor additional information.

Thanks for pointing that one out. I think I'll keep an eye on it as it matures. Note this warning from the readme:
