I created an extension for Firefox and named it "Tabs Tree". The extension is for managing browser tabs and representing them in the form of a tree structure. But now I think that I should have named it "Tab Tree" (without "-s"). Like "apple tree" or "orange tree". But I used google and found usages of "Elements Tree" (https://docs.tibco.com/pub/spotfire/5.5.0-march-2013/UsersGuide/id/id_elements_tree.htm) and "Nodes Tree" (https://documentation.devexpress.com/#eXpressAppFramework/CustomDocument113328) expressions. But also usage of "Element Tree" and "Node Tree".
Are both variants correct to use with that meaning? Or those people who used "Elements Tree" and "Nodes Tree" were wrong? And can I leave "Tabs Tree" as it is as it would be troublesome to change the name now?
