I checked again Var Toy, due this thread https://www.photools.com/community/index.php?topic=6198.msg42855#msg42855
And I must say, this App is really good.
We can use it in different manner in each App-Panel.
All text within stays, also when I close IMatch and reopen it.
I would say, it can be a depositary for different things, not only variables, but also for personal text, reminders (birthdays, phone nummers ;) ) and IMatch-specific reminders (check event xy, add categories for month December ...).
Though I would have some wishes for VarToy (some simple text-formating or break lines and so on, but maybe there is something like this and I have not found or I can try doing it myself ;D).
If you think, this could be something for you, check out once Var Toy.
