Two suggestions for editing features.

[uNderdog_101]

I have two suggestions for features that would help me quite a bit.

1. Probably the simplest one to implement; a box below the A and B boxes that indicate how much time is marked in between A and B, in seconds and frames. So I don't have to do that math in my head.

2. The more complicated one; multiple cuts. I want to be able to load a file, mark a selection between A and B, put that selection in a list/queue, make more selections, and then output those selections into a single file.

Agreed, sounds a good idea

Keep in mind:

Avidemux is a simple tool for simple video processing tasks. The keyword here is simple: it does not offer tools like a timeline, multitrack editing, you cannot freely move or splice audio and video clips from various sources. However, Avidemux allows you to do elementary things in a very straightforward way.

Time permitting: you may never know and see some suggestion implemented.
