Change classification and color scheme of maps

[elninohm]

Hello. Thank you for your flexible and great website
I see you add the option that we can change the classes and colors of data in the maps. It is so good for me. this ability can be more complete. I tried to change the color gradient of accumulation map for myself. But it is very difficul to do it manual. Sometimes the numbers of colors do not change or when I do it manual, sometimes it is not a rational gradient. For example i want to have accumulation rain map with this colors. I think if you can add some prepaired gradient with automatic classification by enter number to re arage it, it would more interesting and useful.
Thank you very much
Best regards
