Support Everything v1.5a new sort functionality

Everything 1.5a significantly expands the options for sorting searches, for example by path length, and allows multiple sorts to be on top of each other. Currently, there doesn't seem to be a way to take advantage of this in Flow Launcher, as the sort options are limited to those in the Flow Launcher dropdown in the Explorer plugin.

Peeking around the Everything documentation, it looks to me like this might require an SDK update to the Everything 1.5 SDK as well as additional code along with any Flow Launcher UI work so it's probably non-trivial, but are there any plans to support this functionality eventually or any known workarounds to use the newer sort options?

Start with the Explorer plugin's Flow Launcher sort dropdown and compare its current options with the Everything 1.5 SDK documentation. Trace how sorting is passed to Everything, then determine the UI and SDK changes needed for path-length and multiple-sort support. Done means the newer Everything sorting options are available through Flow Launcher.
