-Macros:
-
-// - When changing the macro definition, all instances are not updated.
-
-// - If I have macros \newcommand{\foo}[1]{[#1]} and
-//   \newcommand{\foox}{\foo{x}} then when an instance of \foox is drawn on
-//   screen, there are two black frames.  While this is "correct", it is
-//   annoying.
-
 - LyX crashes when you define a recursive macro
 
-Misc:
-
-// - If I have x_{1}^{2}, I put the cursor before the 2, and press backspace,
-//  the result is 'x2'. The correct result should be 'x_{1}2'
-
-// - If I mark some text and then press ^, then the marked text is deleted.
-//   The correct behavior is to put the marked text in the superscript.
-
-// - Pressing <down> when cursor is in subscript will move the cursor up
-//   (to the base of the subscript) instead of exiting the inset.
-//   The same problem happen in fractions
-
-// - When you press the mouse just to the left of the middle point of
-//   some char, the cursor will be positioned to the right of the char.
-
 pp - It is possible to put two or more consecutive spaces in math text mode
 
-// - Text in superscript is not smaller than normal text.
-
-// - After insertion of \sum, the cursor is in invalid location
-
-// - The height of the frame is often wrong (e.g. x^2)
-//    For example $\sum x$ in an inline formula
-
 - InsetFormula::validate is broken
 
-// - Changing math space length by pressing the space-bar key doesn't work
-!!  it's M-m space now. 
-
-// - The drawing of decorations on screen is very different than latex.
-//    (a low priority bug).
-
-// - If I change '\alpha' to bold, the result is \mathbf{a}
-
-// - Just moving the cursor in a math inset causes changing the buffer status
-//   to (changed).
-
-// - disable the insert->label menu item when in inline formula.
-
 
 Eran Tromer:
 
-// - When exiting the formula during selection, the anchor moves to the
-//   left of the formula and there's no way to go back.
-
-// - Scripts are too large. $\log_2$ exceeds inset frame (non-displayed).
-
-// - You need two <right> to get past \vec{v}, and all sort of other
-//  insetish behavior.
-
-:: Not a bug.
-
-// - \vec{several-characters} doesn't work. \overrightarrow does.
-
-// - When the cursor is in a subscript (and either isn't at the end of 
-//   the subscript or there's no subsubscript), pressing <down> should
-//   try to *really* go down (to the next line, or denumerator, or 
-//   whatever). Currently it goes *up*. Ditto for superscripts.
-
-// - When choosing to insert "\left\Vert \right\Vert" parenthesis using
-//   the maths [sic] panel, a "\left( \right." is inserted instead.
-
-// - Formula inside tabular cell: red frame of cell inset and purple 
-//   frame of formula can overlap, causing leftovers when leaving 
-//   formula. To get an example, insert a 1x1 tabular into a new document,
-//   enter the cell its cell and press 
-//   M-m ( M-f 1 <right> <right> <right>       (zoom=100, screenDPI=100)
-
-// - When selecting multiple cells in a array using the keyboard, <left>
-//   etc. should can move whole cell at a time -- no need to navigate 
-//   within cells.
 
 - When selecting, maybe give a visual indication of the "original" 
   anchor, when it differs from the "actual" one.
 
-// - Placement of cursor using mouse is seriously broken.
-//   Example 1: large fractions.
-//   Example 2: type into a new document: 
-//   "M-d xxxxxxxxx <right> M-x footnote-insert"
-//   Can't reach most places in the formula using mouse.

-// - when you get into equation array mode, the previous equation(s)
-// remain(s) unaligned. I would be soo much faster to have LyX pick the
-// last equal sign from the previous line as a reference for the alignment
-// (and a good heuristic for the 80% of cases, with the advantage that we
-// don't lose anything enforcing it). This is another case that slows down
-// a lot when typing because, as the previous one, requires going back
-// and correcting.
- 
-// - the movement is sometimes clumsy inside this arrayed equations: ie.
-// C-a (or "home" are understood as "beginning of the formula" instead of
-// "beginning of the equation". Again, a lot of movement has to be made.

 - I suggest creating a different "kewybinding namespace" for the formulas,

  C-?) thath currently do their job PLUS getting you out of the formula.
