 Unknown release (on a scratch-an-itch basis)
- - Silently drop content inbetween SCRIPT tags (can be generalized to allow
-   specification of elements that, when detected as foreign, trigger removal
-   of children, although unbalanced tags could wreck havoc (or at least delete
-   the rest of the document)).
  - Fixes for Firefox's inability to handle COL alignment props (Bug 915)
  - Automatically add non-breaking spaces to empty table cells when
    empty-cells:show is applied to have compatibility with Internet Explorer
+ - Convert RTL/LTR override characters to <bdo> tags, or vice versa on demand.
+   Also, enable disabling of directionality
+
+Encoding workarounds
  - Non-lossy dumb alternate character encoding transformations, achieved by
    numerically encoding all non-ASCII characters
  - Semi-lossy dumb alternate character encoding transformations, achieved by
    encoding all characters that have string entity equivalents
- - Convert RTL/LTR override characters to <bdo> tags, or vice versa on demand.
-   Also, enable disabling of directionality
 
 Requested
  - Native content compression, whitespace stripping (don't rely on Tidy, make
-   sure we don't remove from pre tags)
- - Win32 Phalanger C# binaries
+   sure we don't remove from <pre> or related tags)
+ - Win32 Phalanger C# binaries (?)
+ - Remove redundant tags, ex. <u><u>Underlined</u></u>. Implementation notes:
+    1. Analyzing which tags to remove duplicants
+    2. Ensure attributes are merged into the parent tag
+    3. Extend the tag exclusion system to specify whether or not the
+    contents should be dropped or not (currently, there's code that could do
+    something like this if it didn't drop the inner text too.)
 
 Wontfix
- - Non-lossy smart alternate character encoding transformations
+ - Non-lossy smart alternate character encoding transformations (unless
+   patch provided)
  - Pretty-printing HTML, users can use Tidy on the output on entire page
