quick-insert VS foundryvtt-terrain-ruler

You are right, it's a feature within the pf2e game system. I don't know an addon for that but i recommend https://gitlab.com/fvtt-modules-lab/quick-insert. It opens a search bar when pressing ctrl+space that finds actors, items, stuff in your compendium etc.

MrPrimate, the guy who wrote/maintains the DDB importer, has indeed put out a pathbuilder importer. I haven't tested it, and the last time someone tried to maintain a similar module they gave up because the foundry system moved too quickly to keep up with given their effort, but this is very in his wheelhouse, conceptually, so maybe this time'll be different. It really isn't that much effort to transfer choices from PB to Foundry though, especially with a little QoL support.

Quick Insert

Search Anywhere will search the contents of Journals (the GitLab page states "Full text content search inside Journal Entries, Item description, Actor bio & Rollable Table description (world's entity only)"), but only those that are world objects (not those in Compendiums). If you have tried it before and it hasn't worked for you, you might look through its settings. It doesn't look like the author of Quick Insert will implement the same feature.

Quick Insert for quickly finding spells, monsters, even rules in Foundry.

Terrain Ruler is the other mod that works with Drag Ruler and ETL, again, that mod has not been updated to V10.

"It would be so cool to use my Streamdeck to interact with Foundry." -There's a module for that. "What if difficult terrain was automatically calculated?" -There's a module for that. "I wish my players could change their token for when they're sitting." -TAMFT. It's just crazy.
