(D&D 5e) Player Inspiration Pool

Hello frens! Been trying to figure something out to make a house rule idea I really like work in a Roll20 game interface. The House Rule I want to implement is basically that the GM sets a bowl in the middle of the play area where every player can reach it and have some sort of token in said bowl to be used as a communal Inspiration Pool. I was thinking about just adding a deck of inspiration tokens but it seems a little difficult for me to manage (maybe I don't really know how to use decks well?). Regardless, I would really appreciate any advice anyone could give me regarding implementing this house rule. My must-haves are these: 1. The number of inspiration tokens currently available to the party must be clearly visible to every player. 2. Players would ideally be able to interact with the pool themselves to take/use an inspiration token. 3. The pool itself would be able to have a variable number of tokens in it at one time, from no tokens in it at all to a maximum of four. 4. The DM can quickly add an Inspiration token to the pool at any given time. Bonus points for chat commands that announce when an Inspiration Token is taken and by which player, as well as for when the DM adds an inspiration token to the pool. Thank you all so much for your kind help!

If you have many archived player accessible sheets already like a player useable macro mule, add a repeating box to it or add hero points to it and use that combined with chatsetattr to allow you and the players to modify the value.  

Hey thanks for your reply! I'm a little lost in the jargon but I'll look it up and try to find my way around! Alternatively if you have the time and patience to explain it in simpler terms for a beginner I'd really appreciate it, but absolutely no pressure of course!

Without going into API scripts and such, the simplest solution would be a token that has control set to "All Players". Pu it on any map you are on and set bar 1 (for example) to the Inspiration pool (max 4). Players can tell by looking at the token how much inspiration is left. If you attach the token to a shared character sheet and set it to be in all players' journals, any player can pull a copy onto the VTT to check. Just make sure the bar is linked to an attribute in this case, so that the number will always agree across multiple instances of the token.

Oh that's brilliant and simple! Thanks so much, I'll do that!

You could also make an inspiration deck, deal 4 out to yourself and the players can then right click your hand and choose to ask for a card from you.  This would get around the need to have the token on every map.  

Oh that's brilliant too! I'll try out both solutions and see which one works best for me and my players! Thanks so much for your help and advice! :)
