Advanced CMS features tracking issue

[joepio]

This is a tracking issue for (advanced) headless CMS features that I think Atomic-Server will need. Most of these are encountered in tenders and competitors.

• [x] Create and edit articles / pages / menu items
• [x] Versioning
• [x] Real time sync / live collaboration
• [x] File upload & management
• [x] Rights management
• [x] Full-text search
• [x] React (@tomic/react) + JS (@tomic/lib) + Svelte (@tomic/svelte) integrations
• [x] Filters & sorting
• [x] Import & Export data
• [x] Easy to use article editor #435
• [ ] Image resizing / compression endpoint atomicdata-dev/atomic-server#529
• [x] Table editor
• [ ] Aggregation counts for facets #569
• [ ] Groups for rights
• [ ] Custom process flows (including drafts #467 , reviews, pipelines)
• [ ] Copyright notice management (e.g. in files / images)
• [ ] Linkchecker. Could be a plugin that checks all markdown fields for links, fetches these, creates warnings if they have issues. Maybe it sets a dead-links property on the resource, which in turn can be retried through a collection.
• [ ] Community tools (e.g. surveys, forum, chat). Unclear how, exactly, but it definitely involves users creating accounts and having a profile.
