 * More filters
+  * By directory
+  * By directory sub-match
+  * By regex match of whole path
+  * By syscall
 * Output format so that it is compatible with the flamegraph grapher
 * Capture more tracepoints? See comments in tracepoints.c's header.
 * Automatic testing (integration tests)
 * Performance benchmark...
