Point and click interface

[miguelmarco]

Would it be possible to have some kind of mouse interaction for typical basic operations? I mean actions such as:

• separate a goal that is a conjuction (that is, call fconstructor)
• separate a hypothesis that is a conjunction (that is, call choose or cases')
• Create two goals from a hypothesis that is a disjunction (that is, call cases)
• introduce the first part of a goal that is an implication (intro)
• introduce arbitrary objects for a goal that is of the form ∀ x,... (again intro)
• choose the corresponding objects from a hypothesis of the form ∃ x, ... (choose`).

There are other situations where this kind of approach could be used, but I just listed the most evident ones.

I am thinking on something like this: if you have a situation like the ones before, you can right-click on the corresponding part, and a menu shows up proposing the corresponding action (maybe with some fields to fill with the names of the hypothesis/objects that will appear), and a button to trigger the action. When the button is pressed, the corresponding tactic is written and executed.

The rationale for this request is that these are actions that are repeated a lot, and writing them once and again ends up being very boring. Also, maybe this approach could encourage users to explore the proof status with more attention (or maybe not).

I am happy consider and merge contributions in this direction, but this is unfortunately out-of-scope for myself to work on
