Description Vincent Boudry 2023-05-04 14:29:42 UTC 
Description:
Working with large presentations (≥40 slides) is cumbersome and heavy.

Several improvements are possible. 
My impression is that a hierarchy in slides of could help.

- having a master presentation and link to sub presentations 
  - this is partially available https://bugs.documentfoundation.org/show_bug.cgi?id=142904 but lacks the possibility to follow the link and edit the source.
  - Dragging a file in the preview could create a link or 
- having the possibility to export a selection of slides to a new file, and replace them by a link to this file
- optionally, have this hierarchy visible in the preview,
  - and foldable (this is feasible in Keynote, see attachment)
- partial saving as automatic saving might take very long. Reduction of the presentation help but 
  - in practise, only a couple of items are modified between saving. 
  - for example, can compressions of unchanged images be saved and reused ?
  - sub-presentations could also be a candidate



Steps to Reproduce:
1. Create a large presentation, with large images
2. Work for while with it


Actual Results:

Did you try use "Tools - Minimize Presentation" tool for decrease the presentation weight?

And please in the future - file different reports for every idea.

Added UX team for discussion.

What is the actual problem? Slow processing, I guess. If so, please describe your presentation, how do you use templates, background images, hardware etc. everything that could explain decrease in performance. Maybe you can share an example.

In a recent survey [1] participants reported to have the same number of slides as you, in average, but performance issues was not mentioned often.
