Synchronize Desktop and Android

I started the topic Use Storage Access Framework for best privacy and compatibility to suggest that logseq adopts the best methods for file handling in Android. Provides best chances for low friction compatibility with new versions of android and gives a load of different options for interacting between apps (ever more as scoped storage is increasingly enforced by newer android versions). Votes on that feature request should help get it more visibility and (hopefully) implementation of SAF stuff in logseq
