5 Second delay before taking shot with Fujifilm Tethering

I Love that LR finally supports Fujifilm tethering with my GFX 100s, it starts quickly, and live view and autofocus works beautifully, It's great to have another option besides Fuji's Tether plugin. I have just one major bug that I found while using it:

There is an exact, persistent 5 second delay between pressing the shutter button in LR and the camera autofocusing (5 second pause) then taking the shot, is there any way to get rid of this delay? It transmits the entire 100MP raw file into LR in less than a second when using the shutter on the camera or the Fuji App! Please can Adobe remove this unneeded 5 second delay?

Also is there a way to temporary disable the new tether feature and use the Fujifilm Plugin like in the last version? Currently it kind-of works, but live views have to be synced, and it duplicates all the imported files.

Auto-import with the separate app works, but that adds another 10 second delay to pull in each file after the shot!

Also it would be nice to be able to use the filenames from the camera directly instead of being forced into renaming to (DSCF0001) or a custom sequence, will be a major issue if I have to grab images from the memory card and ALL of the filenames are different!
