Status on generic storyline editor, simplified:

Persistence:
For version 0.1, will be using user-activated object serialisation.
For version 1.0, will be using atomic timestamped patches that are pervasively stored, backed up, and synchronized when possible.

Platform dependence
All versions will likely be platform independent, both with regards to OS and processor. Python and clutter will be utilized for the bulk of the work.

Programming Language dependence
Python will be utilized for main development, allowing for mid-level portability.
For version 0.1, this is not a concern.
For version 1.0, XML export must be implemented and fully supported.

Network dependence
This will not be necessary for any versions. Version 0.1 will not support it.
For version 1.0, it will be necessary for pervasive synchrony.

Command response delay
No delay is acceptable in any versions.

User Interface
0.1: Basic experience with a basic font. Functional auto-placement and folding algorithm.
1.0: Pixel-precise user-customizable fonts, dynamic and fluid interface experience, with panning, zooming and scaling all incorporated, and dynamic folding and placement of everything. Placement structures and colour schemes incorporated to allow writers to use their visual memory.

Backwards and forwards compatibility
0.1: No focus is given here for this release.
1.0: Fully forwards and backwards compatible, as well as allowing for different branches when necessary. A simple tool for merging, splitting, and maintaining synchrony across versions and branches.
