Allow to make "sorting groups" of games to sort easily by series or other arbitrary categories #5031
Description
Problem description
Suppose I have several games in a series with titles that don't follow a proper naming convention. For example the games of the Tomb Raider series on GoG (Rise of... Shadow of the... etc). This leads to situations where parts of the series might not be listed anywhere near each other, let alone in the correct order.
Feature description
It would be nice to have a way to select all of the games in this series and group them together so they are all sorted together.
I'm imagining just ctrl+clicking some games, right clicking, and choosing "Add to sorting group... new group..." and then they appear in the library together with a border around the group, sorted into position by the group's name (for example as the "Tomb Raider Reboot" group).
And inside this group you could sort the games in whatever order you like (right click to sort by name, release date, or by just dragging them around and ordering them arbitrarily).
Alternatives
I realize you can probably work around this problem somewhat by just adjusting titles, but this would interfere with automatic artwork selection and might get confusing fast. Grouping games and being free to sort inside those groups would be much more robust for keeping things neat and organized.
