I think its known "styels" (based on bitmaps) can not resize or "gradient-tweak" in 1.7. Please keep that in mind.

New or just remarked: Text will not save as style anymore. Well, i can save text-formats... but often the old styles was much more faster and intuitive to use and reachable ANYWHERE. In 1.6 a "style-saved" text got its font/size/color/distance-paragraph-break... and some other useful attributes. And this Style(S) was AVAILABLE in all new and old documents. The only thing i would "mark" they old styles had a cog instead a sample... and yeah, as all style presets, they can not reordered or named greater 8 letters... or subcategoryiezed....
I really hope you will make the better (not perfect) preset-system from synth-texture-filter also implement for styles, brushes, macros... afaik, but for the day please give back just the option to save a text just as style instead this over-complicated text-format, which is maybe useful for Publisher, but for Photo maybe overkilled, at least not so fast and handy than the old style!
