Would this be a workable approach for the OP - wrap the app launch
in a generalized mechanism, let's call the mechanism Larry (as I
abhor the imprecision that comes with "it", and have no better name).
Larry handles each attempted application launch for the seniors.
Here's what I envision happening:
Larry looks at the proposed app, and if that app has one or more
running instances, display a dialog, with a suitably large font,
with a clickable list that distinguishes each running instance
of the app. At one end of the list, distinguished visually in
some way from other items in the list, is a "nope, none of
these, start a fresh new instance" list item. Clicking a list
item or using the arrow keys and the enter-key would switch to
that instance or launch a new instance of the app.
Larry should have a way to back-out of any action at all - "cancel".
And a Help button that has both an icon (I favor a question mark)
and a (largish) text label to go with it.
Larry could be assembled using bash, kdialog, and some tools
such as xmumble and grep, right? (Mumble is a place-holder for
an actual executable name. This isn't a fully worked example).
#!/bin/bash
itemlist=`xmumble | grep mumble | sort | ...`
myitem=$(kdialog --menu "Click what you want" $itemlist)
# activate the selection or launch new app
/usr/bin/mumble myitem ...
