User interface improvements for colors and channels

If I may, I'd like to add my two cents as to how I think the UI of this module could be improved to better usability and allow for more features to be integrated.

Non-UI related comments in quotes

This feature request is based on comments and discussions in other threads. But has a number of new ideas / features that are unrelated.

The current 'Groups' and 'Channels' collapsed field sets should really be implemented as tabs under admin/settings/adsense. 'Groups' should be renamed 'Colors', or 'Color sets' or something similar.

The number of groups (8) and channels (7) should not be set anywhere by a variable. Rather, on a new installation there should be only 1 default group, and no channels. An adsense admin can then create as many new groups as they wish, and up to 200 channels.

Whether this data is then stored in variables table or a new adsense table is of no significant relevance to the UI, however I suggest if the variables table can support the largest possible amount of data that 'Color sets' and 'Channels' may need to store without exaggerated cost to performance, then there is no reason not to. That's what the variables table is for, I believe.

Every channel and group should be identifiable by an alias/nickname in the UI.

Channel ID in adsense.module is pointless when google's channel ID is also a unique integer. Using an integer-ID in the UI is problematic, whether it's a one or ten digit integer. Hence drop the adsense module channel ID, introduce a channel alias, and obviously maintain the google channel ID.

Separate but related features:

• The 'Color sets' interface should ideally have a color picker introduced on the color set edit form, like the color module has implemented on garland theme settings form. A preview area would be nice, although possibly conflicting google adsense' T&C's.
• It'd be nice to be able to import color sets from google.com/adsense/code, or existing embedded adsense ads in templates or other pages / sites. This feature would be similar to what Wesley proposed as option 3 The importing function would need to parse the code and store the settings as fields for editing (with either the current interface or the color picker as proposed above). It would discard some settings from the google generated code such as the ad dimensions and channels.
