Use the [Bidi Mirroring](http://www.unicode.org/Public/UNIDATA/BidiMirroring.txt) file instead of my old [openClosedUniGenerator.py](https://github.com/robotools/defcon/blob/master/tools/openClosedUniGenerator.py) for the open/close methods in `font.unicodeData`. Maybe add a new method called `mirroredRelativeForGlyphName`.

Point Observation

Almost all objects in defcon participate in the notification system (which is based on the observer pattern). Points are the main exception and it has been a problem for years....

Speed up UFOZ read/write.

4

Reading and writing UFOZ is extremely slow when only part of the wrapped UFO data have been modified. This is partly due to some issues in ufoLib (which I will...

These should be replaced with their counterparts in `fs`. `testTools` has some functionality that can be used for this.

Optimize

15

This is a general issue for ideas on optimizing the overall speed of the objects.

In the UFO 3 branch, the glyph object loads contours shallowly to try to reduce the initial loading time. This is done here: https://github.com/typesupply/defcon/blob/ufo3/Lib/defcon/objects/glyph.py#L410 With this: https://github.com/typesupply/defcon/blob/ufo3/Lib/defcon/pens/glyphObjectPointPen.py#L40 When contours are...

Don't create a new glyph and copy the data from the old glyph if all of these conditions are met: 1. The glyph does not belong to another object. 2....

Allow observation of classes.

6

In many cases an observer needs to observe all glyphs in a font. That's only possible by subscribing to each glyph individually. That's cumbersome and becomes problematic when glyphs are...

Update documentation.

This ticket is a place for me to keep track of all the things that need to be documented. new API new granular notifications representations

Stop posting notifications to dead references.

3

When a reference is dead, the notification system skips it. It needs to be caught and removed from the system so that the looping is minimized. There is already a...
