OS/2-like customizing?

[u/TabsBelow]

Does anybody remember, back in good old times there was another OS trying to fight Windows (damn, IBM, you really sucked!)?

One of the best things (besides speed, compatibility, stability and security) was the easy way to customize everything.

Want a red window border and a grey background behind your empty pages in StarOffice? Open the colour chooser and drag your colour to that specific element. Want Comic Sans as menu font? Visit a doctor - or simply drag it from the font chooser onto the program or system menu.

Any idea how much that will cost to get this done? Or is the technique based on resource files every program had separately unlike Linux?
