 # Tools for analyzing Chrome's binary size
 
 # Super Size
 
 Collect, archive, and analyze Chrome's binary size.
 
 ## "archive"
 
 Collect size information and dump it into a `.size` file. Mainly consists of
 symbol information parsed from a linker .map file.

+1. Better Linux support (clang/lld).
 1. More `archive` features:
 
   * Find out more about 0xffffffffffffffff addresses, and why such large
     gaps exist after them.
-  * Use nm to get the full list of symbols that share the same address.
   * Collect java symbol information
   * Collect .pak file information (using .o.whitelist files)
   * Collect .apk entry information
 
 1. More `console` features:
 
   * Template Symbols - shows when templates lead to code bloat.
   * Duplicate Symbols - shows when statics in headers are an issue.
   * Overloaded Symbols - shows when overloads are excessive.
   * Per-class / namespace size (no way to distinguish class vs namespace).
-  * Per-Chrome package (Chrome-specific grouping. e.g. name prefixes).
   * CSV output (for pasting into a spreadsheet).
+  * Make Where\*() methods filter recursively on already-grouped SymbolGroups.
+  * Add symbols.SplitByNamespace() - which will be like GroupByNamespace, but be
+    recursive.
 
 1. More `html_report` features:
 
-  * Break down by other groupings (e.g. create from nested `SymbolGroups`)
+  * Break down by other groupings (Create from result of SplitByNamespace())
+  * Render as simple tree view rather than 2d boxes
 
 1. Integrate with `resource_sizes.py` so that it tracks size of major
    components separately: chrome vs blink vs skia vs v8.
-1. Speed up some steps (like normalizing names) via multiprocessing.
 1. Add dependency graph info, perhaps just on a per-file basis.
