Windows 10, Obsidian 0.13.14 on Desktop
I don’t recall vanilla obsidian behaving this way. Maybe you were using a plugin.
Item 1 sounds like Advanced Tables, but I can confirm this is broken in v0.13.14 unless “Use legacy editor” is enabled (along with a few other plug-in behaviors which have been noted elsewhere)
I’ve seen this just now so maybe it’s no longer relevant for you, but note that the RTL plugin works properly with the new editor now.
