Option for not displaying activities with a specific activity tag

[Vangelis Karafillidis]

I think that the implementation of an option for not displaying specific activities would be useful in some situations. For example an option for not displaying activities with a specific activity tag would solve this problem. What do you think?

Edited: I am referring to the generated timetables. Especially the html ones. I am not referring to the way the activities are displayed in the FET UI.

Can you give an example in which situation you want to use this feature? I am interested in that, because there are maybe better other variants (like merging activities).

The only situation I have so far is this (but it refers in fact to subjects, not activity tags.):
The head master has only a very low number of activities, but he is at school of course every day. So adding only his activities while adding constraints for ALL teachers like min hours per day and max gaps it is too strict. My solution so far is adding him "office" hours. Of course that looks a bit strange and I simply delete that office hours after importing them into TiTiTo.

Hello Volker.

I think that in Germany you have Music Schools. My suggestion has to do with Greek Music Schools. This type of schools has many private-like (one teacher with one student) activities for musical instruments (piano, violin, etc). Most of the time, at least two teachers (timetablers) prepare the timetable. The first teacher prepares the timetable for the group activities, and the other teacher the private-like activities. These two "sub"-timetables "intersect" on the hours (time slots) that the groups (for example A1, A2, etc) are available for these private-like lessons. But, the timetable can be solved as a single one with FET. In this case, the individual students need to be added as subgroups of the tree structure of the schoo.
However, there are many cases that the timetabler of the musical instruments "sub"-timetable needs to make changes on this specific part of the timetable, without making ANY changes on the group activities "sub"-timetable. The subgroups-time-horizontal is the most useful one, since it presents the activities of each one of the individual students. But, the problem is that this view of the timetable presents ALL the activities, i.s. the private-like activities, along with the group activities for each one of the students (for example: Math, Physics, Sports), which of course is completely correct. Unfortunately, at the same time this attribute of the html view of the timetable is confusing for making MANUAL changes on the private-like lessons. Actually, what is convenient for the timetabler is a timetable with only the private-like music lessons.
So, if the timetabler could assign an activity tag for this activities and if FET had this feature I suggested, it would be very easy for the timetable to export this type of the timetable.
Another variant might be not to display the activities of each super-set, but only the specific activities of the students. In this case an option to omit (not display) the activities of the super-sets of each student (i.e. group and year) should be implemented.

Interesting. I think I understood. Sadly I can't see an other good variant. We should add your suggestion to the TODO list.
