Your 'HelloWorld' program has become so successful that you've expanded it to take in the whole solar system, with a different section for each planet. Congratulations!
However success brings its problems, and one of these is a workspace containing lots of files: far too many to have each open in a tab at the same time. CodeLite helps here by reloading the last-used tabs when it restarts, but it would be nice to have more: a group of Mars-related tabs, another for Venus...; and be able easily to switch between them.
Well you can. Open all of the tabs you wish to save, and click
Save tabs as group
In the dialog, unselect any that you don't want to store, and choose a name and path. That cluster of tabs will be
available for reloading in the future, using
Load a group of tabs
Choose a group, or browse for others, and decide whether the tabs should replace any current ones or merge with them (not advisable in the case of Mars and Venus).
