You don't have to like Mail App. I'm not forcing you to. I hope you're not forcing me to choose and like a third-party email program. Alas, I am already forced, by Microsoft. Off the bat, you win.
All I'm asking for is that Microsoft's "Send To > Mail Recipient,' found in its very own context menu, to call up Microsoft's very own Mail App. I would like the ability to send a file out of an Explorer when I see the file. For now, I must open the Mail App, click through folder levels to find the desired file, and attach it. Several clicks, compared to one. (Same for browser-based email.) "First-world problems?" Probably. But it seems easy enough for the professionals.
It is beside the point to say, "Just because an e-mail program comes with Windows 10 (or any other
version of Windows), that doesn't mean it's the e-mail program you should be using." Rather, my point is: Because an e-mail program (created by MS) comes with Windows 10 (also created by MS), I expect that it should work with the rest of the OS. As the consumer and loyal user of Microsoft Windows, I have the right of this expectation. As another commenter said, it is just a matter of a few lines of code.
Maybe you can help me: Is there a way to set the Send To default to go to Gmail in the web browser? The Mail App shows that one of its defaults is "Mail To." As far as I know, this pertains to email links found on webpages.
