Typora has a very nice spellcheck integrated. It works just like the spellcheck in Pages, in safari when typing. It’s a spellcheck system that feels like system-level (because how consistent its look and behavior are with different apps).
If only Obsidian can have that integrated. Right now, there is a red line, but we need to right click to look for suggested corrections.
Also, no native auto-capitalization. The third party plugin doesn’t work perfectly. Try typora and type “e.g.,” or “i.e.,” in both Typora and Obsidian with “Easy Typing” plugin and you will know what I mean.
