This is a special post for quick takes by RobertM. Only they can create top-level comments. Comments here also appear on the Quick Takes page and All Posts page.
We shipped "draft comments" earlier today. Next to the "Submit" button, you should see a drop-down menu (with only one item), which lets you save a comment as a draft. Draft comments will be visible underneath the comment input on the posts they're responding to, and all of them will be visible on your profile page, underneath your post draft list. Big thanks to the EA forum for building the feature!
Please let us know if you encounter any bugs/mishaps with them.
Small bug that might confuse users: the new draft shows up where I wrote it, only after I reload the page.
Repro:
1. On post page write comment replying to another comment
2. "Save As Draft"
3. Observation: draft does not show up under the parent comment
4. Reload page
5. Observation: draft does show up under the parent comment
Expectation: at 3., the draft should appear under the parent comment
If I had to hazard a guess, I would suspect what the codebase calls "a terrible hack" is at fault. If I were to venture further, I would guess getDraftSelector implies the default is include-my-draft-replies, while line 343 of the terrible hack implicitly assumes drafts are excluded by default.
