It's OK if you write the actual bug report in the email, and just attach
the SGF and text file.

Regarding the bugs:

Should be fixed as I wrote earlier.

Settings->Analysis->Move limit only indicates how many moves should be
saved in the analysis. 

When generating the list of moves for "hint" or the analysis, gnubg will
do:

(a) generate all moves
(b) evaluate all moves on 0-ply
(c) prune (e.g., pick all moves with equity diff less than 0.16 to best
move, but 8 moves at most)
(d) evaluates the moves from (c) at 1-ply
(e) prune (pick all moves with equity diff less than 0.08 to best move,
but 4 moves at most, and only iff "no 1-ply prune" is not selected)
(f) evaluate moves from (e) on 2-ply
(g) etc etc.

> 2  The resulting list is not ordered

gnubg orders the list as follows

(i) the level of evaluation (e.g., 2-ply is better than 1-ply)
(ii) cubeful equity
(iii) cubeless equity

That is, 

Ply     Cubeful Cubeless
2       +1.0    +0.9
2       +1.0    +0.85
1       +1.2    +0.95

*NOT*

Ply     Cubeful Cubeless
1       +1.2    +0.95
2       +1.0    +0.9
2       +1.0    +0.85

Can you provide a specific example? E.g., a position ID and match ID or
a SGF file.

I found that the Chequer play, Cube action, and dice rolls check box
items were not saved. Others?

> 2  The export submenu

I found that "Show evaluation parameters", "Show rollout parameters",
and "Show detailed probabilities" for both moves and cube were not
saved. Others?

> 3  The evaluation submenu

Can you be more specific?

The opacity from Board, Border, and Points are not saved, as they are not used.
I'll see if I can remove the opacity property.

I agree wrt the analysis submenu. Other menus?
