Currently: when we register a link and enter a Marker, the system simply allows any set of characters, promoting an easy redundancy of registered Markers, because the user does not remember, precisely, which Markers he has previously inserted in other links. Implementation suggestion: implement the “intuitive bookmark” feature, in such a way that, when we start the imputation of each character, the system brings an automatic list box of links already used, with initials composed of the characters already imputed, to allow the user to choose a given previously registered Bookmark, before the effective insertion of the Marker, either by Enter or by the comma (automatic separator) - this will necessarily avoid or minimize redundancies in Markers, and this feature will be equivalent, for example, to Competitive service "Bit.Ly “, which I have already declined, due to the technological potential offered by this Service (Short.io).
