Mailplane 3.6
Uncomplex has released Mailplane 3.6 with added support for accessing Google Inbox within its own tab (though attachments viewed in Inbox still cause Mailplane to freeze, a known issue that Uncomplex hopes to resolve soon). The Gmail-specific email client also now enables you to return to regular zoom level more easily (View > Actual Size), fixes a crash related to printing from Google Inbox, deletes pending download history items when quitting Mailplane, and fixes a number of bugs and visual glitches in OS X 10.11 El Capitan. ($24.95 new, free update, 21.5 MB, release notes, 10.9+)
