Create a fixed Viewer pane instead of spawning new ones #1421
Description
Is your feature request related to a problem? Please describe.
I'd like to be able to wrangle the amount of 'Viewer' tabs that are created. I make a lot of tables with flextable and each time I make one a new Viewer pane is spawned.
Describe the solution you'd like
Ideally, I would be able to have one Viewer pane that gets updated - similar to how the R Plot pane works. If that's not possible, then it'd be good to be able to define which group new Viewers get opened in.
Describe alternatives you've considered
I'm not aware of any other alternatives to this - I've looked around the settings and I can't seem to find anything that controls this.
Additional context
None - I'm happy to work on this as well, if you could point me in the right direction.

#1707 and #1741 now reuse Data Viewer and List Viewer panels when viewing the same object or its descendants.
This issue concerns generic HTML/flextable Viewer panels. Those still go through showWebView(), which creates a new webview panel on each call. The data/list reuse changes therefore do not complete this request.
Keeping this open for generic Viewer reuse.
