Preventing duplicate memos

[christophe-lejeune]

When the user creates a memo, the software should check that the proposed name does not exist yet. If it is the case, the creation should be interrupted and the user prompted that a memo with the requested name already exists.

Such a feature is preferable to a drop down menu suggesting an existing name when the user is typing the name of the memo to be created. Indeed, proposing to create a link with an existing memo may suggest that repetition is not a problem (or, even, may be interpreted as a encouragement to re-use existing memos rather than creating a new one). The design of the UI should of course discourage such (wrong) interpretations.

This feature could be improved by checking for existing memos before the user hits the create button. This could be done by the same mechanism that autocomplete uses.

Maybe the dialog prompt could provide a button allowing to grounds the current memo in the existing memo. Such a feature would require to check that the type of the existing memo matches the type of memo that the user is attempting to create.
