Remote Desktop Manager is great for running many sessions at once by using it's Embedded/Tabbed display mode. It's especially true when using multiple remoting technologies at the same time. No longer you have to dig in your task bar to locate the session of interest, you have all of them running in tabs in the same tool that you use to launch them.
But when you reach a certain number of running sessions, it may become difficult to identify them using only their name. To improve on the user experience for those of us that love embedded sessions, we created a feature to Filter the tab pages, it is called the Tab Page Category.
The tab settings are found in the User Interface side menu of your session properties.

Simply type a name in the tab page category to create a tab group when launching an instance. You can see it in action in the image below
Tab groups displayed - All selected
When the All group is selected, it performs no filtering. When you select another group, it hides all the sessions that do not match with the filter. In the example below, I've adjusted two sessions to have the same category.
