Hello @brichet,
Today on another notebook, I had the old behavior of not getting back to the previous fragment but beginning of previous slide. Just checking: this was merged in jupyterlab-slideshow=0.3.1, right? If yes, I'll try to minimize my notebook and post it here.

@nthiery no, we did not released this change yet. I'll do a 0.3.2 today and let you know.

[nthiery]

Ah, this explains that. Good. Thank you!

[brichet]

@nthiery it has been released in v0.3.2

[nthiery]

Great! I confirm that it works smoothly!

Including in JupyterLite.

Ah, well, up to a new glitch: the notebook toolbar does not include anymore the deck icon. But one can still run the slide show through the command palette or configure settings. Weird.
