Hello, Steve.
Yes, it looks like maybe you don't want BookMacster launching in the background for your use case. Click to read this here Help Book section:
Running it in the background to learn what you did, how to see BookMacster again, and how to undo it.
If you did not switch on the menu extra, and don't remember the global keyboard shortcut that you set to show BookMacster's
Floating Menu, you can remove the
launch in background preference by doing this:
Activate Finder.
Click in the menu: Go > Utilities. A window will open.
Find and double-click to open the app named "Activity Monitor". A window will open.
Type
BookMac into the search field. A line for
BookMacster will appear alone in the table.
Select the line for
BookMacster.
On the left side of the toolbar is a button with an "X" icon. Click that button. A sheet will appear asking if you want to quit BookMacster.
In the sheet, click the button:
Quit. The BookMacster line should disappear from the table.
Back in that Finder window, double-click to open the app named "Terminal". A window will open.
Copy and paste the following "command" into the Terminal window:
defaults delete com.sheepsystems.BookMacster launchInBackground Hit
return. There will be no indication. That means: "It worked".
Launch BookMacster. Now it should launch into the
foreground, like a normal app again.
