File structure cache and offline mode

hi, is there any plan to support file structure cache and offline mode?

The cloud storage become larger and larger and many could storage providers start to provide their own software to mount as disk. And almost all of them have these two features.

It is very important to search content and open big file fast when we get a large cloud storage. Currently using RaiDrive to search content on mounted storage is very slow …

Will you improve on these functions?
