Add a per-slide timer to speaker notes?

[kquinsland]

I really really really like the speaker notes view on marp! The clock/elapsed time is <3.
I have one request/idea that I think could make the speaker notes view that much more powerful...

Allow me to indicate the maximum amount of time that I want to spend on this slide so this can also be displayed in the speaker notes. I don't need a timer progress bar (although that would be awesome). A simple 00:05 / 00:30 display to indicate that I've been on this slide for 5 seconds so far and I didn't want to spend more than 30s would be adequate!

At present, I do something like this:

<!--
[30s]

This is quick about me; spend at most 30s here; mostly to allow time for people to scan QR code on screen...

-->

Which does put a [30s] right at the top of my speaker notes. This has a few big down sides, though:

• I have to mentally keep track of the elapsed time when I entered this particular slide
• Then do the mental math to figure out what time I should be off this slide by

And ideally instantly and "in the background" while I continue to speak about the slide's content.

If there was a per-slide field like timer that I could configure like so:

---

<!-- _header: Current section: foobar -->

# Advantages of foobar

- blah
- blah

<!-- _footer: something snarky here :) -->
<!-- _timer: {max:30s, warn:20s} -->
<!-- 
If the audience was receptive to earlier interactive portion, ask $questions and link reply to the advantages.
...
-->

---

That would put an "elapsed time on $this slide" counter on the speaker notes view. After I've been on this slide for 5 seconds, the section of speaker notes would display 00:05/00:30 and at 20 seconds elapsed on this slide, the 00:20/00:30 would turn yellow (customizable via some css class, of course!) and at 00:30/00:30 the timer would be red as would any "overage": 01:10/00:30 (if I spent 70 seconds on a slide that was only supposed to get 30...)

Your suggestion would be able to implement with Marp Core, with using the custom local directive, the handmade Marp plugins, and making the custom presentor tool.

Marp team is focusing on simple interface for slide writing experience, the presentation support for presentor is intentionally minimum. From the classic Marp app, we have learned that the scope creep will cause bankruptcy of the project. 😢 So probably we would not lead that.

We want to leave enhancing for presenters to third-party Marp tools or external tools for presenter integrated with Marp.
