quick-insert VS rolladvantage-token-stamp-2-foundry

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.

There is also a module for Token Stamp 2 integration, though I don't personally favor it over Tokenizer and can't speak to its quality/ease-of-use, even though I like Token Stamp for making tokens outside of Foundry.

Token Stamp 2 for quickly making tokens out of image files, really nice if you host Foundry from a separate device and you can't be bothered using rsync all the time to send new files over :)
