Grail — tail, filter, and live follow

Usage

Right-click a file (Explorer, editor tab, or inside an open file) → Grail: Open File.
Use the file link at the top of the Grail panel to open the source file.
Type in the filter bar to narrow down lines — plain text or /regex/flags.
Adjust Lines to change how many lines are kept.
Click the line number next to any log line to open the real file at that exact line in a normal editor beside the viewer.
Click Wipe File Contents to clear the log (when possible).
