I've been looking for an app that would let me keep track of the items that I needed for hideout upgrades and barter trades, but none of the ones I found worked for me, so I made my own! It will let you select what Barters or Hideout upgrades you are looking to complete, and will give you a full list of all the items you will need. It's really useful for a second monitor if you want to know at a glance if that lightbulb is useful or not.
If you want to check it out, I would really appreciate any feedback, it's at
Thanks, and I hope you like it!
