Is your feature request related to a problem? Please describe

Dendron directory structure make storing a vault in a cloud drive (eg dropbox/onedrive/gdrive) challenging.

1. The .next directory is 1+ gigs
2. .dendron-cache has contention between machines

Describe the solution you'd like

A clear separation of folders between vault content which should be shared, and build/local data that shouldn't.

Describe alternatives you've considered

A clear and concise description of any alternative solutions or features you've considered.

[SeriousBug]

Thanks for the feature request, we are planning to improve Dendron's usability in synced folders and we'll keep this issue in mind.

a current workaround is to deploy published pages using Netlify, Render or Vercel. Then your Dendron folder would not be flooded by build data.
