Features & Capabilities

TST Indent Line is a Chrome extension that adds visually clear indent lines to the Tree Style Tab sidebar, similar to those found in Visual Studio Code. It requires Tree Style Tab version 3.8.5 or higher to function correctly.

For users who want indent lines visible in private (incognito) windows, the extension requires additional permissions to access tab information. Simply enable "Run in Private Windows" for TST Indent Line and adjust the Tree Style Tab settings to allow notification messages from private windows. This enhancement improves tab organization and navigation within the sidebar for a more efficient browsing experience.

Is TST Indent Line Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

TST Indent Line requires a few sensitive permissions. Exercise caution before installing.
