Idea Summary
Each APEX application page in Application Builder has a Page Navigation drop down that allows either entering a Page Number directly or selecting a Page from the Page drop down that includes each page name. Then click Go to be taken to the selected Page.
Add this same navigation drop down to the Application's main page (where Shared Components, Import, Utilities, etc. is available).
Use Case
Presently, to navigate directly to a page the page number or a search term has to be entered in the search box, click go, and then click on the page from the list. If not sure of the page number, then you have to get the search term in the page name correct to get it to appear in the list.
If the navigation were added to the search bar as an alternative method, you could also enter the page number directly and select from a list of all pages making it easier to get to the desired page.
Preferred Solution (Optional)
Add the Navigation drop down found on individual APEX pages to the main application page. Seems like a simple thing to do.
