Hi Yuri,
so good to see you swinging your virtual icon brush so much :)

Hi,

Attached is the proposed icon for Formula tool pane (instead of current
edittext.png).

Thanks in advance for a review.

My review (sorry, I push for perfection, so nitpick quite a lot):

* Potential mismatch in symbolism
At least in Calligra the formula shape itself has the root symbol as main
symbol in it's icon, so now using the sum symbol in the icon for the tool
could confuse the user due to the slight mismatch.
Does anyone know what is used as generic symbol for formulas in other
office/report/math tools? Ideally would be something similar, so learned
knowledge can be applied (like everyone uses the floppy disk for saving,  
even
if young users have not even seen a real one before).

MS Equation 3.0: red alpha under square root.
MS Equation Editor 2007/2010: cyan pi with a black border
MathType: cyan big sigma with a blue border
OO.o Math/Libreoffice Math: gray button with black "a" under the square  
root
Kile: blue x red = blue y
LyX: cyan big sigma with a blue border

* does not work on all UI backgrounds
surely there are not many people with blue backgrounds :) but the icon  
does
not work perfectly on dark backgrounds in general, its contures are hard  
to
see. Ideally there would be an outline which adds a sharp contrast, so  
the
actual icon shape can be seen with any background.
Have not complained about this with the other missing icons, because they
needed to match an existing match, so I ignored this problem there
* is blue a proper color code?
wondering why you chose blue. While it stands out and helps to discover  
the
tool, it also makes the icon... really stand out and somehow not fitting  
to
the others

Most of forementioned modern editor tools have blue/cyan icons. Sans/Serif  
flavors attached.

* editing symbolism
what about putting a small caret (the Capital-I-with-Serifs-like looking
cursor) into the icon (behind the sum symbol in your proposal), to  
signal the
editing? Should not make the result look to complex IMHO
Cmp. the icon of the text editing tool

None of the known editing tools has a cursor symbol on its icon.

I attached something along with this proposal, but I think it's ugly (I am  
not an artist, rather mathematician).

So your first proposal is better than nothing, but would not make me  
happy :)

P.S. BTW if the Formula shape is not switched off as unusable, can the
missing Formula shape icons (sent earlier to this list) be committed?

I would be happy if they are, I think they match the existing icons well  
and
would close the holes in the Formula UI without any traces :)
Guess they need to be LGPL'ed as well?

They are derivative work from the existing icons.

Inge is the official maintainer of the Formula shape, so his final call I
guess.

Cheers
