KDE applications 18.08 comes with tons of new stuff:
Kmail, KDE's email utility, has enhanced its travel data extraction engine and supports more ways it can give you useful information about your trips. Dolphin, the multi-purpose file browser, now adapts better to your preferences when searching for and viewing files. Gwenview, KDE's image viewer and organizer, has improved most of its options, making it even more powerful.
