As a non-programmer, but still with some old time technical knowledge, I am quite disappointed in this current release (115.5.1). This machine still is running Windows 10.
The ability to change fonts, and font sizes, in the menus (too large) as well as the displayed emails (too small) is certainly not obvious. I did search the support, and either did not understand the commentary, or the suggested solutions did not work. Power is one thing, but you need some simplicity for the average user.
The "save as" for attachment seems to just do nothing and not saving anything anywhere. Particularly with all the silly "pictures" in the "signature" these days, this is a problem. I did not find a suggestion for that one.
