Please, make Chattable interface more friendly for the library clients:

// Chattable is any config type that can be sent.
type Chattable interface {
	Values() (url.Values, error)
	Method() string
}

Currently, Telegram bot has many methods that are not implemented in your library.

I try to switch from RamBox to Ferdi. However I have several services with the same icon (slack, nextcloud). It would be a great help if I just cloud add a small textual label next to, under, over the icon. Don't care where.

Sorry that this is not a pull request, my JS/css knowledge is insufficient. I tried copying the tooltip to a div. Didn't get the correct tooltip and a misplaced div...
