@@ -8,17 +8,22 @@ DETECTION ENGINE:
 - implement src and dst ports as prefilters
 
 - speed up initialization with many address groups present
+- do a sort-insert for the temp address lists: sort it big to small to speed up later inserts
+- siggroup(uri)content comparison can benefit from a list size counter
 
 WU-MANBER:
 - Consider using dynamic/variable hash sizes. A wm_ctx is quite big (512kb) even for small pattern sets.
 
 ADDRESSES:
-- support [1.2.3.4,2.3.4.5] notation: cleanup (memory!) and unittest
+- support [1.2.3.4,2.3.4.5] notation: unittest
 
 MAIN:
 - move packet preallocation into it's own function
 - create a cleanup function
 
+THREADING
+- Add pre-threading initialization API e.g. for Sig loading on Detect.
+- Add post-threading deinitialization API
 
 CUSTOM LOGGING:
 - idea: add a logging module that can be told to output things based on flowvars
