Is your feature request related to a problem? Please describe.

The filters in some widgets are using Case-Sensitive.
For example - Types widget, Flags widget

Describe the solution you'd like

Enable case-insensitive search in them all

Describe alternatives you've considered

Best option will be to set case-insensitive by default and add a little button to toggle the mode. But that is only a nice-to-have

Additional context

It will be also nice to make sure that the filters enable Wildcard Matching
