Here are some suggestions based on my recent experience in teaching 
LibreOffice and writing a python macro :



Impress : work on "papercut" bugs
----------------------------------


1 - Animations sets for a text box with several paragraphs don't affect 
new paragraphs (not inherited)
https://bugs.documentfoundation.org/show_bug.cgi?id=57581

This is the most annoying problem that new users face :
  - they create a slide with few lines of text,
  - they add an animation on the text, to make it appear line by line
  - they test : it works correctly
  - they add one line of text (inside or at the end)
  - they test and boom... the animation is "broken"
  - they make a pause, then... close impress and open powerpoint...



2 - Editing: Text spacing changes when click in textbox
https://bugs.documentfoundation.org/show_bug.cgi?id=89060

It is a subtle but very annoying visual effect.






Python macros
----------------


I had to create a macro embedded in a file.
As I had not written basic for a long time, I tried to write it in python.

The fist problem is that on Ubuntu, it is necessary to install a 
specific package 'libreoffice-script-provider-python'


The second problem is that, by default, there is no tool to integrate a 
python macro in a document.
I found the APSO extension [1] that allows that and is very useful.

I found some difficult points in writing python macro with that extension :
  - after modifying a python script, you have to close and re-open the 
odf file
  - some inline documentation is missing : about API, and some sample code
  - the context (available via XSCRIPTCONTEXT) is missing some API, 
compared to basic





So here are my suggestions for GSoC :
  - allow an easy activation of python support : a simple button would 
download and install all necessary packages
  - integrate the functionality of APSO (to allow embedding/managing 
python script in odf file)
  - remove the need to re-open the odf file before using a new version 
of python script



Other points can be done directly in the current extension :
  - add some inline documentation about API [2]
  - add inline documentation on both ways to use python script :
    - an external script that connects to LibreOffice
    - an internal script that get called by menu/button
  - allow to create scripts empty or with comments (that provide 
minimum documentation and good practice)
  - add a library of sample code (a list of "how-to ?"), that can be 
easily copied in script files


Adding API to the context (available via XSCRIPTCONTEXT) can be done by 
working on LibreOffice code :
/usr/lib/libreoffice/program/pythonscript/py






Cheers,

Michel
