SUMMARY The KDE Connect app should be able to replace both the keyboard and trackpad of a laptop. Currently, the remote input is similar to a trackpad, however, a version similar to a real trackpad (multi-touch gestures etc.) would be helpful. Additionally, being able to quickly switch to keyboard input would help, as the feature is almost always rendered useless if the keyboard must be used for most inputs
Regarding the keyboard, please see also Bug 391083 and Bug 423531. Regarding the remote input, please see also Bug 451360.
