I hesitated to post this under problems, but I reckon it’s more of a nuisance than a problem.
I had real difficulties to work with the spell-check function (the one called by F7 - not the immediate, which underlines wrong words and works fine). Repeatedly, I thought that this feature doesn’t work at all, because none of my corrections were retained when I dismissed that window. Why? Because there is no button called “Done!” (or so) to commit the changes - instead, one has to awkwardly click the menubar-button and select “Exit” there. Not very transparent or user-friendly … Or did I miss something there?
Another suggestion: as a user who regularly writes in at least 3 different languages, it would be nice to have a way to change the spell-check language with just one click. I’d suggest a pop-up list ion the bottom of the composing window, to set the language of the current mail. Thus, an eventual defined default language would remain untouched.
Or, if anyone has an idea how to easily change the language without having to resort to the menu, I would be very interested. For me, the spell-check was a major reason to come to emclient - among other nice features.
