Anyone have a suggestion on creating an app that can solve these kind of exercices?
The user has to connect a dot on the left with a dot on the right. But... they must also be able to delete a connection they made. It should also be possible (if I allow it) to connect a dot on the left to multiple dots on the right.
Maybe there are built in tricks like "hey use this in ZIM, it will be the easiest way to do it" that I'm not aware off?
Connectors should be able to handle this... let us do a little test run - have not used them in a while.
I @EducaSoft I made this already idea the same

I made this simple version with ZIM Connectors()
Nice. Your example only connects if right. It sounds like Bart wants to be able to connect if wrong or right... and be able to change your mind. Maybe trigger a correct if it is correct - or press a check button to see if correct.
Here is an example...
I made also this
with connectors
clicking a green line becomes grey (not clickable anymore) + lines can be removed by clicking on them
image example : no connectors but shadows connecting with speech shadows
This one works and illustrates the basics, thanks Dan
Karel,
NICE your underwater schatkaart + check. I did manage to do some stupid moves, but hey as long as the system detects them as "not correct" it's perfectly ok.
Your code also demonstrates coloring the lines and removing them. Actually, this is about 99% what I need.
Dan wins in terms of code size and simplicity. You win in terms of functionality. Now its up to me to combine 
Thanks for your kind words.. belgian code friend
Very nice and simple @Abstract
Love ZIM from the first day!
You might have seen that I seem to have disappeared from earth since march 22nd. I had to pause all of my programming activities for a while because our school was informed that we would receive a full school inspection during the week of May 4th to 8th. As a policy staff member and ICT coordinator/mentor for new teachers, that meant all of my time would go into preparing for and handling the inspection. Fortunately, it is over now. We received a very positive inspection report, and we are very proud of that. Now I can fully focus again on creating educational activities with ZIM.
Woohoo - congrats, Bart. Keep up the good work.
