Yes, if you could calculate how long your fuel time is. But I think this feature would be most useful for small quick stages. I have had things crashing because when spamming Space there's a little delay.

Bump for interest.

What it could look like: (I like making reference images... Easier to show people what you actually mean.)

Just that for the player there's no scripting involved, just a few mouse clicks. But yes, that's how it would work.

Would it be possible to add a small gear-icon or something when hovering the mouse over the staging in the VAS? And that icon lets you put small "micro stages" like a little timer bar. That would mean you don't have to dash space and loose time separating objects from you craft. Example: At launch first stage, first command when pressing space will activate engines, 0,3 seconds later rocket will be released. Example 2: Failed launch, command when pressing space will be to activate side boosters of capsule, 0,4 seconds later capsule will detach will full force and send sideways away from the craft. This would be a small compact addition to the staging, and not visible until you toggle the specific stage you want to edit, then between the parts inside that stage you get a small bar saying "0.0" which would be instant when pressing space. Adjusting to 0,5 would be a half second between the parts to activate in that stage. This way, you could do semi-automatic launches, and without any delays of pressing space and save fuel and time. Thoughts?
