This Obsidian plugin attempts to make tab labels unique by prefixing the filename with the parent folders. If adding one parent folder does not result in unique labels, another is added, and so on.

Note that I'm using Bradley Wyatt's Autofit Tabs plugin in this screenshot.
Search "Unique Tab Labels" in the community plugins browser in Obsidian and install from there.
Simply enable the plugin. There are no settings.
This plugin modifies Obsidian's tab labels by patching the rendered tab-header DOM. Obsidian does not currently expose a public API for changing built-in tab labels, so future Obsidian updates may break the plugin.
