Things I'm maintaining.. (Patreon)

Clash!
- An encounter manager for mostly for 5e (but could be used for anything) initiative, monster stats/stat blocks and quick player-inputs for basic information (HP, AC, Initiative, etc.) Also let's you create/save monster data or import from pre-made collection/SRD material.

Rumble!
- A chat extension that allows for 3d Dice rolling, advanced dice rolling via chat commands, direct messaging, safety cards and some specific rolling for BRP and Call of Cthulhu games.

Marked!
- A system agnostic condition labeler that let's you slap statuses on tokens quickly and easily.

Scry!
- A token/image management extension for quickly finding things in large scenes and/or 'vanishing' them for later use where people can't see them.

Smoke & Spectre!
- The successor to Dynamic Fog - this is a joint project with Doggosaurus.  This one does a lot, so just.. check it out.  The Spectre side of things let's you make a token visible to only the players you select.  So if you want to fill a room with ghosts that only one player can see - this is how!

Ticker!
- A simple timer extension that syncs up to your players. Also has alarms/warnings.

PDF!
- A local PDF viewer, in case you want to keep your source material in the OBR window and not have to tab through a bunch of things.

Flip!
- Let's you flip a token left/right, automatically order tokens based on their z-coordinates so that ones in 'front' are displayed appropiately, and also BIND two tokens together - so that when you flip that token, the other one shows! (Like binging a Druid and a Bear, so you can flip them around for wildshape.)

Theatre!
- A message delivery system in the style of old school JRPGs.  Type in a message, select a token and have a dialogue box with a character portrait show up on that players screen.  Immersion!

Calendar!
- A calendar system similar to DonJon's Fantasy Calendar (and can also import from), built into OBR and saves the current date to your room.

Chronicle!
- Character Sheet management. More to come!
