Taskpane in a separate window

[edvardasvabuolas-ebiquity]

Hi everyone,

I've developed an Excel add-in with a taskpane for internal use at our company. It includes a few charts, and sometimes it would be really helpful to display the taskpane fullscreen on a second monitor.

While Excel does let you drag the taskpane into its own window and resize it manually, the window doesn’t have minimize/maximize buttons, and it also doesn't respond to the Windows + Shift + Arrow shortcut for moving windows between monitors.

Ideally, I'd like to find a way to open the taskpane in a completely separate window while still having access to Excel.Context. Alternatively, if that's not possible, maybe I could add a button inside the taskpane that resizes the window to predefined dimensions once it's undocked.

I looked into window.resizeTo(), but it only works on windows created via window.open(), which isn’t the case here. I cannot use window.open() because then I would lose access to Excel.Context.

Has anyone tried something similar like running a taskpane in a separate window or found a good workaround? I'd really appreciate any tips or suggestions.

Thanks!
