[RCD] Would you do this as a plugin or skin?

Hi all, I had a question. Switching from a horizontal to a vertical mailbox list (a three column layout), would you think this should be done through a plugin or through theme?

I played with it when creating a theme but was thinking that maybe this would be better done through a plugin.

• Aside from the obvious UI changes, to do this well one should really change how the message list table is displayed (since a narrower list doesn't make sense with the same table view). As far as I know, this is beyond what a skin can do.
• In addition, switching the layout makes more sense to do it through Settings > Mailbox View > Main Options rather than by switching themes.
• Lastly, this feature would then, in turn, be also available to any theme.

Any thoughts? Would this make sense to be done through a plugin or do you think this is better left to skins?

Thanks! PS: I'm not a programmer, so unfortunately I don't know how to do it myself. Would this be hard to do? Any volunteers? ;-) _______________________________________________ List info: http://lists.roundcube.net/dev/
