1) Have the Inbox node pinned as a tab and use a custom layout
2) Play a track from inside Inbox
3) Switch to another pinned tab with a custom layout
4) Use the "Locate playing track at source" command either by double click in player controls panel or through the context menu
Result: It creates new tab for inbox and locates the playing track there
Request: If a pinned Inbox tab already exists, switch to that tab and locate the playing track there
The main reason I would like to have this is, currently when it opens a new Inbox tab, it (as expected) doesn't use the custom layout I have in the pinned Inbox tab.
EDIT
Several clarifications
