I just switched a customer who was on M365 to SM and their first question was why is it so complicated to open an attachment when in the webmail interface. It needs to be downloaded, then opened from there. Why can't it just open directly from the server into the viewing app, whichever it may be, including a new tab in the browser (or pop-up). PDF, PNG, JPG, etc., can all be opened directly in the browser. Please add this to a near-future release, or I'll never hear the end of this one.
