For next MBS FileMaker Plugin we have a new feature for you: Window.PositionNextDialog function.
You can call this function in a script just before FileMaker shows a dialog. The plugin will watch for new dialogs to show up and the next dialog to come is adjusted. We check if you provided a new X/Y coordinate and if so move the dialog. If you got us a new width and height, we resize the dialog. And if you set the center flag, we finally center the window on screen.
Works fine on MacOS and Windows so far in various FileMaker versions. We hope the function will help people with multiple screens to position the dialogs better.
Coming with next prerelease. Please do not hesitate to contact us questions.
PS: We added already the option to pass 2 for center parameter to center in front of FileMaker window.
