Feature Idea: Check spelling

Summary:

It would be nice if there was an option to enable spell checking. It'd be enough to check the spelling and show errors during editing only.

Here's how Jira does it when you edit the summary on a ticket, for instance:

The native mac app does offer spell checking in the menu but it doesn't have any effect (I suspect that's a default menu option and not hooked up with the web view).

How important this is to me and why:

Importance: Low

Use cases:

1. I want to avoid typos to prevent misunderstandings when other people look at my cards or comments
