 ### What is this?
-This is an attempt by me to make a font that is just a box with the unicode code point inside. These are usually not in a font but rather programmatically generated by programs as they encounter characters that have no associated glyph.
+This is an attempt by me to make a font (collection) that is just a box with the unicode code point inside. These are usually not in a font but rather programmatically generated by programs as they encounter characters that have no associated glyph.
 
 ### Why?
 Because I wanted zero width characters in my code to be not zero width. I was trying out vss code (pretty nice imo) and found I should be able to use some CSS magic to make it so that certain characters are displayed by this font. ([see also](https://graphicdesign.stackexchange.com/questions/95687/making-a-tofu-font))
 
 ### Things that need to get fixed
  * It's not very readable when small. Make better tofu template
- * Fontforge python lib is sometimes screwy. Find better library
+ * The size of the generated font collection can probably be made smaller (for example by excluding unassigned characters)
+ * The progress bar isn't smooth since the fontforge lib provides no way to measure its progress when loading the generated .sfd files
 
 ### This is stupid
 Yeah probably, but for its very specific use case it's not terribly bad.

 I used python3 for this, it may work in python2. If it does not please feel free to make a pull request to fix it but I am not actively supporting python2.
 
-The syntax for the program is as follows. `gen_tofu.py 0000 FFFD -o`
-`0000` is the start
-`FFFD` is the end
-`-o` makes it output otf rather than ttf (should make this default, ttf screws up more in fontforge than otf)
