Use MobileFrontend
Now that Special:Translate is available on mobile, MobileFrontend could be enabled on translatewiki.net. Translation is a not very complicated action, which can be done on the go.
What’s the problem with it? Maybe that should be fixed—Special:Translate is much more used. Also I don’t think it’s hard to be fixed as Special:MainPage seems to have an absolutely responsive design.
Is there any way to make MobileFrontend opt-in through the preferences (for testing)? Or can I get the source code of Special:MainPage to test on my own wiki? (Currently there’s no link on Special:Version, please link to its Git repo there if possible.)
Adding mobile target to ext.translate.mainpage.styles
and jquery.uls.grid
resolved the problem (except that it’s not entirely scalable, i.e. the header is at least 600px wide, but I think that’s acceptable); however, I don’t know if there is some reason to not load the ULS grid style on mobile.
I created a Phabricator task for it so that ULS developers are also notified, and it can be linked in Git commit messages.
