HT Letterspacer is a tool for spacing fonts, that works on finished fonts as well as during development. The first public version works as a macro for Glyphs and uses that application's glyph categories and subcategories feature, but the method is adaptable to any editor or programming language.

Version 1.10

• Copy parameters to clipboard (thanks mekkablue)
• Robofab no longer required for drawing _areas
• No more code repetition

Version 1.11

• Code merged in one script file
• createProofGlyph renamed to drawAreas
• Fixed bug with empty tabular field
• parameters can be float, tabular value is integer

tabVersion for suffixes:

• This part is not working and returns error when .tf or .tosf is present
• Suffixes intended to be tabular ('.tf', '.tosf', etc) need to be in a list in the initial config and not in the middle of the code
• When the UI, if Tabular is activated it should change the boxes width even for glyphs with suffixes
• TabVersion should be easily fixed from config, to work in monospaced fonts
