Ever tried the Dropbox add-on for gmail? I dream about that for OneDrive. That's the last bit that prevent me for dropping... Dropbox.
I actually could consider using another mail client if I learn this is available outside gmail.
I share files with clients every day, link sharing, no sign-in. sometimes those files are in different folders.
This app is very simple, but very efficient. IT shows you the last modified files, so most of the time you just have to click on it, and it add a link in your mail, with the file name, not an lengty http adress.
I know I can do the same by clicking Ctrl+K and adding description and link made in file explorer but seriously:
-go to file explorer
- locate the file
- right-click
- share
- go to parameters
- unclick "can modify"
- go back
- copy the link
- go back to e-mail
- ctrl+k
- typing a decrpition
- pasting the link...

for EACH files.

I-ve been looking for an alternative for Onedrive for several years, but i'm very surprised and don't find anything. I'm actually very surprised I do not find any mention of this in this "feature request" page. Maybe I did not search for it correctly?
