With Apex Triggers, Classes and Pages you can create a custom list view. This has been fantastic as we continue to customize salesforce with our own customizations and 3rd party vendors.
The Custom Object list does not currently support the fitler. I get a list of all custom objects by default. Until recently we had a list of 51 custom objects. This has sky rocketed to over 190 custom objects due to some installation of 3rd party add ons. This has made finding our own custom objects challenging to find as we have to scroll through the complete list.
Having a custom filter view list similar to what's on Triggers, Classes and Pages will make this a more functionalty page.
