Hi,
Is there any support for undo/redo operations? If not, is it planned?
Thanks

It is already done a long time ago, but the documentation is cryptic: it does not explain it is about undo/redo.... Limitation is published only.
It is also Delphi compatible:
https://www.freepascal.org/docs-html/rtl/classes/trecall.html

E.g. the memo lines are published Tstrings and can use Trecall and actually to quite some depth...Or most of the db related icon properties.
