Tasks
0. Initial loading of test page appeared to hang, but after switching tabs to check the instructions and changing back, the page had eventually rendered. Might be an artefact of the test environment or the device, no biggie. Might repeat this exercise in a sandbox elsewhere if v3 is now live.
1. Adding a wikilink was fine, though I hit several weird/messy VE things unrelated to adding link (formatting, inability to cancel out of workflow and start over). Full-page layout of the search card with separate areas for label, search term, and results was good. Insta-search was disconcerting, probably just because there aren't many pages in the test instance to populate the results and I was just seeing my search term echoed back as a redlink. I accidentally missed the review step because I didn't see the Review Your Changes button (and maybe wasn't reading the instructions closely enough).
2. Edit link label. I found three different ways to do this, one doesn't even involve the Edit Link card. Generally using an on-screen touch keyboard, you have to get used to switching between typing and navigating modalities (i.e. whether or not the keyboard is showing and insertion cursor active), so it's not completely unexpected. Sliding the edit cursor into a link and having the bounding box appear was smooth, I didn't feel unsure about whether my cursor was in or out of the link.
3. Edit link target. I'd already explored, so this was a straightforward exercise of the skills from steps 1 & 2.
4. Finding the selector to switch between Wiki link and External link was easy. Pasted long URL and text box didn't expand. Couldn't scroll text back to start of URL by dragging cursor. After inserting the link, its info card only showed the start of the URL truncated to one line instead of wrapping.
Feedback
1. Tasks clear, except I missed the part about viewing the diff, as mentioned above.
2. Anything unexpected? Different behaviours in typing versus tapping modes was initially a bit WTH? But makes sense after the first time. Tapping Publish consistently resulted in 'Something went wrong | Unknown error, HTTP status 0' though changes often did save. Managed to create an edit conflict with myself at one point.
3. Edit cards generally clear and helpful. Appreciate the change of the first "Publish changes …" button to just the chevron ">". Consistent use and placement of "X" "<" ">" for navigation feels right. Would like URL box to accommodate more text.
4. Apart from error-on-publish mentioned above, was able to complete tasks. Did switch to source mode to fix a formatting problem that couldn't be corrected in visual mode, but this was nothing to do with Edit Cards.
5. Only rarely use Visual Editor on either platform. Adding links and templates is something I find a barrier desktop VE.
