When dragging and dropping from the address bar (the lock icon in Chrome, the settings button or the lock button in Firefox) into a Dolphin window, the menu to Copy Here/Link Here/Move Here appears. Choosing Link Here creates a .desktop file with the name being the URL of the page that was dragged, including the “https://”.

This is not very user friendly. The file's name should be {Location Title}.desktop. That is, the file for the KDE home page should not be named "https:⁄⁄kde.org⁄.desktop", but rather "Home - KDE Community.desktop"

For comparison, if dragged into Thunar, a Create Link window appears prompting for a name for the file and its icon, using the title of the page by default. In Windows's Explorer, the same action (dragging and dropping that icon from a browser) creates a .url file with the name being the title of the page.
