Since I have a dedicated work machine (MacBook), I also would prefer this app run only in the menu bar.
All of my previous time tracking apps (Timelime, Timemator) were menubar apps, where the app is always running in the background, launches at login, and shows only in the menubar waiting to log time.
For apps that run in this menubar mode, an icon in the dock and task switcher (CMD+TAB) is not necessary and frankly in the way, as all can be done from the menubar.
