Please give priority to really finishing existing apps before developing anything new. Examples: in the new email app for Android only plain text is supported, no links. Also: reply to all doesn't work. Both things are essential for an email app. In the previous app it was available. Despite these shortcomings you launched it.
Similar thing happened with calendar. You launched it but the subject line is not mentioned in email notifications, which is essential for a Calendar.

Please, give priority to finishing existing apps with all essential features before launching them and start something new.
