Ability to render only selected clips / a portion of the timeline
Submitted by Jeff F.T.
A checkbox should be added to the render dialog: "Only the selected region". It should be disabled by default.
If the user enables it and there is no interval/region selected on the timeline, it should explain what's missing and point to the user manual somehow.
