As Sakura has pointed out, the options are at the bottom of the page. If you have found them, but don't seem to work, you might need to wait for the arrows to "download". Otherwise you might need to force a repaint by altering one of the other traits that does work.
It shouldn't be too hard to get the card's type to show up automatically. There however are some things to consider here. The ("Illegal") god cards only show that they are Divine Beast-Type, which would not be quite possible to do if the type got automatically concatenated. Another point is that it can be somewhat hard to determine where the type should be inserted. It could be immediately after the first slash, but this comes at the cost of specifying multiple types (or custom ones you'd wish to appear before it).
You could think of various solutions. One such option would be a wildcard that gets replaced by the card's type (does that include pendulum?). Another option is having 2 text fields whose values get concatenated, with the type in between. I'd like to leave it to the community to come up with a sensible option for this issue.
As far as I'm aware, we have no access to the server-side of this site (at least I don't), not to mention the fact that the database (most likely) isn't designed to store the extra information for the link markers and pendulum stuff... though I suppose we could save that data alongside the monster's effect or something like that. And even if we had access, I'd rather not mess with it in fear of breaking it. The host used for the new card maker only serves static files, and thus has no separate database. The cards you are working on can therefore only be saved using localStorage, but that has a size limitation depending on the browser. As such, there won't be any support for storing the information in the cloud for the foreseeable future.
The issue with scrolling comes from the fact that only the [right / bottom] half of the page supports it; if the cursor isn't there, it won't receive the scroll event.
Can you explain in laymans terms why the old card maker could save files on YCM, but we currently can't with the new card maker?
