What's the obessesion with ThemeRoller?

[ozzyjon]

I can see that ThemeRoller is good for:

1. Quickly creating a basic CSS file for a primefaces application.
2. Switching themes between one basic theme to another.

However, there is no fine grained control. So one has to either alter the downloaded CSS, or create a local CSS file that overrides all the bits that need changing. Both of these options make future theme switching difficult and/or creates messy CSS.

Surely a much better solution would to be use a LESS CSS template substituting LESS variables to create different skins?

Am I misunderstanding the power of Themeroller? Has anybody out there created a LESS CSS template for primefaces?
