Enhancement Proposal: possible to allow incremental_lists to select level?

[LumenYoung]

Hi, thanks for this great project and I want to propose a enhancement that might be useful.

Currently the incremental list works for individual slides, however, when there are nested levels of list items, the incremental list will apply to every level. Therefore, is it possible to make them separated? Like for example specify to which level will be incremental.

The reason this one is necessary is because you can't use pause tag in between lists, it will break the layout. Therefore, such control would be appreciated for some nested levels of lists.

So just to be clear, what you'd like is something like "only pause when the top level list item changes"? e.g.

* top1
  * inner1
  * inner2
----- pause here, all of the above show up at once
* top2
  * inner3
--- pause here, shows as one group
* top3 

Maybe what we need is an incremental_list_policy like <!-- incremental_list_policy: pause-all --> being the default and <!-- incremental_list_policy: pause-top-level --> being what I described (and more policies can be added). This could also be configured in the config file just like any other config.

Does this make sense and does it solve your problem?

Hi @mfontanini, nice to see your reply and thanks for this wonderful project.

Yes, I think my request is roughly what you describe. What I see might be a good way is instead of let incremental_list_policy tag to be only true or false, we can accept number which indicates to which level the incremental list should be applied.

The simplest way I see it implemented is <!-- incremental_lists: false --> changed to <!-- incremental_lists: 1 -->, which it receives an integer that indicates to which level this incremental list behavior should be applied. I don't know if that makes sense to your internal implementation but maybe this would save us the trouble to introduce additional configuration parameter.
