CLI Text Improvements
This MR is to improve the error message for kdeconnect-cli. A lot of the critical options in cli require an additional device argument, that is not specified and may confuse the user.
This MR just modifies the help options. Specifically, it stops the display of all options every time the device name/id isn't specified. The main reason for this is to prevent the actual message that'll resolve the error from getting lost with the --help options. Additionally, when the device name/id is missing, it will display instructions on how to specify the display name/id.
Test
The procedure for testing this is similiar to regular development as found on the community website. The new message should look something like this:
This was tested on Manjaro.
