It's a subject I've been investigating months ago as it's a basic 
feature of a slideshow software. But I got no perfect solution yet...
disclaimer : I searched ideas to easily apply appearance animation on 
slide objects and lines in textfield. It's not exactly this bug, but 
it's related.

Beside the UX problem, I've seen something more annoying that seems 
technically-related :
- enter several lines in the main content textfield
- apply an animation : every line will appear after one click
- then insert some new lines in the textfield
--> the existing animation is not updated and provide an awfull order of 
appearance.

This problem is related to technical implementation : there are objects 
of type 'animation' linked to objects in the slide.

In order to solve those problems (fdo#41572 and the update), we need to 
know what changes are possible form a dev point of view ?
here are some questions as a first brainstorm :
- are we stuck with a separation betweens objects in slides and 
animation objects ? is it related to ODF format ?
- can we imagine some visual changes of objects to indicate the order of 
appearance ?

The idea of using master slide for that is interesting, but will not 
cover all uses case (when a user just want that effect on only one slide 
for ex).

This functionality is so important that we have to create a very good UX 
design, and prepare/prototype everything before starting a single line 
of code.

As you may have guessed, I'm interested to work on this subject ;-)
I hope you're ok.

Thanks,
Michel
