Devs have cleared this up. Quote down below but the thread the Dev answered in is found below: https://robertsspaceindustries.com/spectrum/community/SC/forum/3/thread/did-i-hear-that-right/1899312 In the latest Around The Verse on January 24th 2019 a 3.5 flight model improvement was mentioned. Namely that they are adding a push and hold to decouple option. There has been some confusion as to whether this is in addition to the normal 'toggle' option that we have now or replaces it. Could devs confirm either that this push and hold to decouple is an addition to the present decouple toggle we have or designed to replace the decoupled toggle we have, meaning those who fly in decoupled most of the time would have to hold down the button 90% of the time? I think the answer is obvious but it's worth answering IMO if possible.
