I'm coming over from a Presonus 1818VSL to a 896mk3 Hybrid. To be honest, the process has been a bit challenging as there are some MOTU surprises that I didn't expect but I think I'm getting there. I'm trying not to be too critical as I'm used to what I'm used to and sometimes different isn't worse... it's just different!

1) I'm on Windows 7... I've struggled to get my studio PC upgraded to Win10. Is sticking with Win7 a good plan? Does the MOTU driver mess with the upgrade process? Does MOTU software work OK with Win10 at this point?
2) Is there anyway to "hide" unused inputs/mixes/outputs on the LCD interface or in the Windows CueFX app? Not required but, with so many options, it might be nice to hide things when they are not in use.
3) I'm seeing lag between input audio and the LED meters on the unit and on the meters that are in the Win app. Everything is working but the meters seem "behind". Is this normal?
4) With my Presonus, computer output (DAW, Standalone virtual instruments, general audio playback) appeared in the mixer as a separate "input". The only way I've been able to make this work without always having to run in the DAW is to connect the SPDIF output directly to the SPDIF input and "play" everything in Windows out to the MOTU SPDIF output. This allows me to mix the SPDIF input into any one of the available buses. Is there a better way?
Sorry to drag on... I'm new... wanted to say HI and to get some general feedback from more experience users.
Cheers
