I got suggestions from Vangelis Karafillidis, but he said they are not really important to him anymore, so I only added them in the TODO. If users up vote for these, I might reconsider them. Otherwise, I am always reluctant to adding new constraints, since these might be overused/misused and their implementation stressful for me, as I might introduce critical bugs.

From Vangelis Karafillidis (on forum):
Is there ANY way to achieve a constraint like: "Min hours daily with an activity tag for a students set"? The polar
opposite (max hours) is available in FET, but what about MIN HOURS? I was thinking of the equivalent of inserting
for each day the constraint "a set of activities occupies max time slots from selection", but this might severely
slow down the whole process...
Liviu:
On each day, or only on non-empty days?
If on each day: Please try with activities occupy max time slots from selection; it will not slow down the process.
This constraint is highly optimized.

From Vangelis Karafillidis (on forum):
After generating a timetable and pressing the "Teachers" tab, the generated timetable appears in a teachers-days-horizontal-like
form. Of course we can lock and unlock activities on this type of timetable. I wonder if it's easy (for you) to add an alternative form.
I think that the teachers-time-horizontal-like form is easier to use for locking/unlocking activities, since it presents the whole
timetable at once. What do you think?
Liviu: The table might be too large.
Vangelis: I think that it would be easier if this teachers-time-horizontal-like timetable had just the necessary information and nothing more.
I.e. just the teachers' names and the student groups (and the locked/unlocked indication). This would result in a far more "compact" timetable
than including information such as subject titles and tags.
3) 252---------------------------------------------------------
From Vangelis Karafillidis:
Constraint teacher(s) max span per day (max hours + gaps per day).
Also for this he showed how to use tricks using activities occupy max time slots from selection.
