Change your Import button so it allows multiple files to be imported -Android and Windows

That said, I wondered how I could make ANOTHER unique button with this feature and have it listed under the Tools section. And could this be a plugin or a feature standard in future releases? What are your thoughts on that?

You could easily clone $:/core/ui/Buttons/import and patch its code, probably change its icon too, et voilà !
Import button tiddler is tagged $:/tags/PageControls and so would be the clone, effectively making it a page button in the Tools section.
Then, a little configuration in Control Panel → Appearance → Toolbars → Page Toolbar can make the original button invisible, the clone visible, and you’re done.

As for making it a plugin, there are a few plugin building plugins around, like @Mohammad’s Gatha here: Gatha Studio Workspace 2.0.3 — develop plugin using Gatha and Gatha-Thirdflow on Node.JS
Or simple instructions to convert any tiddler group to a plugin by @EricShulman here: Plugin Development Workflow - #6 by EricShulman
