I think its a good idea to have access to them through the Dash.
But there are some problems with these controls:
- no Dash results for the commonly known terminal commands, like:
- halt
- shutdown (without a space between shut and down)
- reboot
- can't suspend or hibernate → inconsistent
- system control icons spam the application lens
Doese a bug report already exists for the 'halt or reboot not shown in Dash' problem?
