If you activate any format with an image field (featured image or gallery fields) and return to either the Aside or Link formats, the image-related fields remain visible.
Can you provide steps to reproduce?
Hey Alex, sorry I wasn't more clear. Reproduction:
After further investigation, there were two actual issues here (both fixed in pull request #2):
We chose not to support Asides in our initial implementation because we find them confusing with Link posts. What should an Aside do? Should it have custom fields?
So yeah, that's probably the main thing that needs to be figured out.
I agree: asides are weird. I think the codex page suggests not showing the title on the front end. Both Twenty Ten and Twenty Eleven use asides - they don't show title in a loop, but do on a single post.
In any case, my patch punts this for now by just allowing currently non-UI'd formats (aside, audio, chat) to just show the title and hide other fields when switched to.
I think as good a description of asides as anywhere is this Matt Mullenweg post from 2004
This predates Twitter and Facebook (at least for the masses) so there is now a huge overlap between status and asides. I'd still like both, with a status being a short note about me and an aside being a short note about anything.
This should be resolved, continuing discussion of #5 in that thread.
