Looking glass: Show number of errors for each extension in extensions tab + other affordances.
Here are a couple of affordances for the looking glass "extensions" tab that would help finding (and so fixing) failing extensions.
Here is a screenshot of looking glass now:
Replace "Show Errors" with "Show Errors({number of errors})" / "No Errors logged":
If an extension has logged no errors instead of "Show Errors", display "No Errors Logged".
If an extension has logged any errors display the amount, e.g. "Show Errors (5)",
The extension name in should be prefixed with a Unicode warning sign
Truncate descriptions if over one line:
Extension descriptions can be many lines, but that makes it hard to scan up and down the whole list, by default these should be truncated after the first line but expandable, e.g. by clicking ellipses, a disclosure triangle or other mechanism.
Lastly, it's hard to see that View Source Web Page are two different things as they only differ by case, there could be more visual separation here (e.g. add a little more some space).
The top of the screenshot I posted above, would look something like this with these changes:
Remina Search Provider
▸ Search for Remina Remote Desktop ...
Enabled View Source Web Page No Errors Logged
⚠️ GNote / Tomboy Integration
▸ Integration with Gnote or Tomboy with GNOME Shell...
Error View Source Web Page Show Errors (5)
