This used to be possible on a mac. In the menu bar you could click the dropbox icon and it would show you the speeds of your upload. Now it just says "syncing" but that isn't nearly as helpful. It would be much more helpful to restore the progress bar and the upload speed. As this used to be a feature, I don't know why it was removed. It was very helpful.
Oftentimes I need to be able to tell clients how long something will take to upload, but I cannot do this as I once did.
Also, I don't know if this is a bug of my system or how it is for everyone (I'm on macOS Sequoia), but there is no upload progress meter. The file uploading either says "waiting to sync" or "synced" with nothing in between. Per the above it would be helpful to have a progress meter that works.
I should say all of this in regards to basic syncing.
