Alternative to PowerPoint for technical presentations?

Question

PowerPoint

Greetings, Habr
At work, I have to create presentations on technical topics (trainings, etc.).
PowerPoint is convenient and nice, but when you need to create diagrams, you have to connect Visio. And when you need to create diagrams with animation, you want to shoot yourself.
Ideally, you want
* the convenience and visibility of PPT,
* the functionality of Visio in terms of diagrams (diagrams are understood as flowcharts, ladder diagrams, network topologies, etc.)
* animation control and a functional animation editor (“paste animation” in PPT2010 is a thing !)
* Properly functioning master slide functionality for quick layout and theme changes.
* local slide library (without deploying a server a la SharePoint) - because. often slides or entire modules are reused.
* the ability to present on two screens (a la PPT Presenter View)
* import / export to PPT and PDF (with the loss of some functionality is acceptable).
Is there something similar in nature? Perhaps the correct PowerPoint book is the answer, which is also accepted.
What was considered:
* Prezzi / Keynote / all sorts of web options - this is for beautiful presentations. And I need functional and supported
* OpenOffice Impress - very simple.
* LaTeX derivatives - very scary :) and output, mostly only in PDF. How to make animations (not just a gradual appearance of something on a slide, but blinking, highlighting, moving) is not clear.

Answer 1

I don’t know if it’s suitable for you, there is a presentation function at docs.google.com
You can also draw there, about animation, it’s hard to say. My friends make presentations there and then share them, give a link to this presentation, it’s convenient that you don’t need to carry it with you and you can watch the presentation at any time.

Answer 2

Prezi.com won't work? Look, the functionality is extensive.

Answer 3

I use beamer (latex package). Presentations are cross-platform and "hardware" (unlike powerpoint's, which in Linux or macos - and even mastdayke, but with a different version of M $ O - with a probability of 90% "float").
Diagrams / graphs are built with gnuplot or MathGL (depending on what beauty is required). Some little thing can be automated at all (call gnuplot when compiling a presentation).
