The one element that would improve the user experience on KDE the most is the usage of the native file open/save dialogs.
This is not only about the look, but also about functionality, e.g. favorite folders.
Implementation is straightforward by using the `kdialog` CLI utility.
One project that does this already is Chromium, using the xdg-utils.
