Unnecessary redundancy with the newly introduced button object
If you have created a button in an editable note and click on it, this does not initiate the requested action as expected, but a context menu opens in which the expected action appears as an option next to "Edit", "Copy" and "Delete”.
I believe that a button should immediately execute the expected action and not by a detour via a context menu.
Only if the page is in read-only mode, the button works as expected and triggers the link when clicked.
Furthermore, this menu is completely unnecessary, since the actions "Edit", "Copy" and "Delete" can also be triggered via the context menu of the block itself. This redundancy should be avoided by omitting that context menu altogether.
Sorry for the german labels, it's "Edit", "Copy" and "Delete".
