Hi Jake,
thanks for the feedback. We know that there are lots of products out there and supporting all of them is a huge effort. That's why we created the "dynamic folder" feature in Royal TS. On our github repo here: https://www.royalapps.com/go/dynamicfolder-samples you can find lots of existing samples to integrate with tools like this. Unfortunately Dashlane is not yet part of our sample collection. We do accept pull requests ;) So if you feel adventurous and want to contribute, feel free to post your sample in our repo.
Regards,
Stefan

Similar to the LastPass integration, it would be great to get support from other password managers.
