VariantEncumbrance VS pf2e

Check out the Variant Encumbrance module! It lets you change the name of the units and the weight multipliers, so it should do exactly what you need it to.

(u/SwingRipper and I relied on the FOUNDRY Remaster names changelog for this poll, available at: https://github.com/foundryvtt/pf2e/wiki/Remaster-Changes )

Error: No system manifest found at https://github.com/foundryvtt/pf2e/releases/latest/download/system.json foundry.js:68325

For example you could grab the link of system.json for version 4.12.9 if you were only on 4.10.4 and install it by pasting it into the manifest URL field and pressing install. https://github.com/foundryvtt/pf2e/releases

With buffs and debuffs, you should be able to drag conditions straight from the ability description in the chat onto the token - there's options in the settings to have them automatically expire and remove themselves or not. For manually adjusting bonuses to rolls I'm pretty sure it's shift + click on the roll (or there's a setting to make it the reverse). It's worth going through the system guide to see how stuff like those work and how to turn them off if you don't want them.

Their changelog doesn’t mention “beta” anymore: https://github.com/foundryvtt/pf2e/blob/master/CHANGELOG.md

If you want to add automation to homebrew traits or new descriptions you'll need to do a bit more than just using the homebrew menu. You can make a module that registers the traits and their descriptions quite easily. It's also the better way if you want to actually organize your homebrew content anyways since you can move it from game to game easily, share it with others, or even get it listed as a module by Foundry. Automation for those homebrew traits is possible, you can look at the Hopefinder module for an example of new traits that also get automated, in that case it was doable because characters in Hopefinder use a "Survivor" class which could contain all the rule elements, but for more advanced automation modules can modify the character data prep though that would be actual coding and not just some rule elements.
