I have not used the feature for long times, what now couple hours and taken couple dozen recordings from 5 min history buffer.

I mostly spent like 15-30 seconds after X event to get to manually trim the timeline to save or export it.
1) It takes too many clicks to get timeline opened, and then to get the trimming options visible.

2) after save / export, when you get next X event and you want to save / export the new part, you open the rec view and you have the previous trimming selection far in the past, and to get clicked to real-time event that happened just 15-30 seconds ago, it becomes challenging. To click "jump to realtime" front of the timeline doesn't always work, and you might end up having the trimming area extended to somewhere else, and then having problem trying to get the trimming area eliminated/removed so you can make a new one.

There is likely more logical purpose how it should be done, but for short couple hours use it doesn't come obvious from the GUI, and requires too much clicking and trying to get the position slider at wanted position in timeline and control the selection.

It shouldn't take much at all to example quickly select "last 30 seconds" or "last 60 seconds" even if buffering is for 5/15/30 minutes etc.
