Attachments in new interface? Or, My carpal tunnels need fewer clicks, not more!

Hi,

Trying to use the new interface as it appears the old one is being phased out. Not thrilled about it but I'm taking the open-minded approach and will give it some time to get used to it. 
My question is - is there a way to streamline the process of attaching files to an email? I always want to upload from my computer. I never want to drag and drop or paste from the web. Can I somehow set that so I can skip the step of it making me select "Upload from my computer" every single time? Thanks for any help!

As some general feedback - I was a huge fan of the old version, and the reason I loved it was its simplicity. For me, the new version has too many features that are uneeded and that I'll never use. Also, I vastly prefer in in-line email preview to the side-by-side that is now the only layout option. I'm sure I can learn to ignore most of the bells and whistles, and I'll probably get used to the preview - but updates that actually make more work by requiring more clicks just to get through all the choices are really annoying. If you were to offer a permanent option for a "Classic View" I'd be all in!

Regards, Ellen
