It would be a nice feature to change the end time of an already in progress or scheduled time lapse.
I assume you want to be able to change it both up and down?
I know this isn’t what you are asking for, but you can initially set the time lapse to be for a longer period than you want, and then terminate it early.
e.g. at set start time for 5:00 PM end time for 11:00 PM and then at 9:12 PM when the “event” is done, you can press the “stop” button, and it will pop up a window with two options:
- cancel (continue the time lapse)
- stop and save (terminate the time lapse now)
If they were going to allow you to change anything after the recording started, the end time is the only one that makes sense to me. It probably doesn’t make a lot of sense to change the interval once the recording has started, same with start time.
