enhanced-terrain-layer VS dragonflagon-fvtt

I got this error too, and it was due to a newer version of the Enhanced Terrain Layer module. Rolling it back to 10.6 fixed the issue. See bug report here.

Enhanced Terrain Layer

For difficult terrain there's also modules... modules for everything! :-) We're using the Drag Ruler module and its addon PF2E Drag Ruler Integration for measuring distances directly. Works great. Now, there's a possibility to use that module with another one for difficult terrain, Terrain Ruler (https://foundryvtt.com/packages/terrain-ruler) and/or Enhanced Terrain Layer (https://github.com/ironmonk88/enhanced-terrain-layer).

In the meantime I'd suggest using DF Architect and DF Curvy Walls to make your life easier. There aren't many maps I've seen which can't have their walls draw manually in a few minutes.

DragonFlagon Curvy Walls - tools for drawing curved walls

Dungeondraft is going to be better for creating full maps. Foundry isn't awful for creating maps, particularly with the right modules - the DragonFlagon ones like Architect and Curvy Walls are great, so is Dungeon Draw for on-the-fly stuff - but at the end of the day, map-making softwares are better for making maps to then export to Foundry for use.

Also, DF Hotkeys should let you rebind many (most?) keys that are already registered in Foundry.

DF Manual Rolls: Allows toggleable behavior for requesting manual rolls, inserting that value into regular roll actions

This is a known issue. Unfortunately I haven't had the spare time to get through my back-log of issues yet. But you can keep an eye on this ticket: https://github.com/flamewave000/dragonflagon-fvtt/issues/297

DragonFlagon Active Lights

DF Chat Enhancements has capabilities for logging in addition to other things, and it does a really good job.

DragonFlagon Chat Enhancements https://github.com/flamewave000/dragonflagon-fvtt/tree/master/df-chat-enhance I'm mostly using this mod for the ability to edit chat messages. The idea is that players would use this to state their actions, and then be able to change their mind later if someone else does something unexpected, or does something that would cause the original actions to "fizzle".
