Bug 432285

Created attachment 135289 [details]
My theme

SUMMARY
I'd really prefer to have separate groups of keys separated by color way easier than the current approach. There should be a predefined way to theme KCalc. My personal preference is the old style calculator, since it is simply more intuitive and easier to navigate through those keys:

STEPS TO REPRODUCE
1. Settings > Configure KCalc
2. Colors
3. Mess around with RGB for each type of element

OBSERVED RESULT
No preview, no clue what a certain change would change within the final result.

EXPECTED RESULT
I would expect this way of setting colors to exist as an Advanced theming, but a simple selection of predefined 3-5 default themes is truly missing (to avoid doing this every time I install KCalc on a different machine).
