==== Background
When I announced add a link is deployed, I invited experienced users to try it out. One of the experienced users sent me a message, complaining it doesn't work at all (see F34477327 for a video they sent me).
@mewoph pointed out in Slack conversation about this that //both// help panel enable preference and newcomer homepage enable preference need to be enabled in order for add a link to work.
It's also worth noting one of the links the help panel has leads to newcomer's preferences, and is labeled "Disable help panel". All newcomers who disable their help panel (AFAICS, in May 2021, it happened for 450 users across all our wikis and 5 cswiki users) will have most of the recent experience we have for them broken without explanation, including add a link. That makes this task worth addressing.
==== Suggestion
Those days, help panel and newcomer homepage are very closely integrated (we have guidance in ordinary suggested edits, which requires help panel, and now we also have add a link, which doesn't work at all with no help panel). That makes me think we should //merge// help panel and homepage enable preferences into one, so this doesn't happen anymore.
==== Proposed design
Move the help panel option to the same place in the `User profile` tab in preferences, and rename the section from being **Newcomer homepage** to something more inclusive of all growth features.
| Default {F34710045} | When newcomer homepage is checked: {F34710043}
==== Acceptance criteria
- All three preferences are under "User profile" tab, with "Default to newcomer homepage from username link in personal tools" toggle only showing when "Display newcomer homepage" is checked.
- "Editing" tab no longer has "Enable the editor help panel"
