agreed, categories could be easier to manage. drag and drop seems like a nice feature, but we'll have to test that to see if such a feature is easy to use for novices.
while we try and figure this out, you can manage your categories by adding and removing tags from your sources.
the fastest way to do this is by clicking on 'edit' which shows up when your mouse hovers over the title of your sources. a drop down box then appears allowing you to add/remove tags (which are really categories).
hopefully this can help you organize your sources for now.
when you mouseover a tag, it turns red with a red line through it.
this was supposed to indicate that clicking on the tag will remove it. it will only remove the one tag you click. when you click on the tag, it disappears indicating that it is removed.
i'll be looking into reworking how sources are managed in the future. any comments on how you would prefer to manage your tags/sections would be appreciated.
