Pretty simple idea for a nice(?) tweak:
It is typical UI behaviour to grey out disabled elements.
What about adding this to Drupal menu edit screens?
Current UI
Proposed UI
In a small menu like this it's relatively easy to spot the disabled items, but in a big menu with longer text entries and especially with also entries, the default (disabled) marking of disabled entries does not stand out very well anymore.
For the screenshot above i used
tr.menu-disabled>td:first-child {
filter: grayscale(100%) opacity(0.3);
}
Maybe the dragging-arrow would need to be left untouched
and surely the exact greying-out effect is TBD,
but before getting a thumbs-up/down i did not want to do anything more.
