Thanks for the plugin and also for taking the time to provide support for it, Jonathan!
I have 2 feature requests, if possible:
1. Instead of selecting just one category to which all posts will be published, I would prefer to have a "support Categories" feature (like there is one for Tags) that will allow to select any category from a drop down, right when bookmarking.
2. I would love to see an auto-complete feature for Tags (like the standard auto-copmplete for Tags on Add/Edit New Post). This would help prevent creating almost-duplicate tags when bookmarking.
Would you consider including any of the above in the future version of the plugin?
