0.0.3 for OSX and Windows is now available.
Please read opening page for more details and for links as things have changed. Delete color_scheme_editor.py from you user folder. Install plugin from github, and then select your platform and download the binary to your user folder (if you wish to put it elsewhere, that can be configured in the plugin).
-Can now create a new theme via the command palette
-Can access the filepicker for the editor via the command palette
-Interlock check for version between plugin and binary
-Fix a bug were the tables weren't getting updated when the global background and foreground settings got changed
-If launched standalone, asks if you want to open an existing theme or create a new one
-If given a .tmtheme file or json file, the editor will now take appropriate action on its own.
OSX seems to hate the wildcards for the filepicker. The wildcards work fine in windows, but weird in OSX...I will have to resolve that at a later date.
