feature suggestion: branch compare

[HackYardo]

A natural and usual using case is that a player want to compare two or three deep Go game branches started from current position, rather than unstoppable forward and backward.

• One solution is to copy sgf file and run two Go GUIs to load them. But a bit unpleasant.
• Another solution is to use LizGoban to copy and switch games at sidebar. But as you may know, LiGoban's sgf file format is horrible and different from Sabaki/Ogatak, it's Lizzie-ish format.

What's the view of Ogatak?

I suppose the move tree is for that? I'm not sure I understand the question.

Sorry for my poor words.The key is one at once or two at once. By a game tree, players can not see two branches at the same time.
A similar question is " I want to analyze a vertex but the AI doesn't consider it". A fair solution it to move a stone at the vertex. But a nice solution it to add to AI's consideration. The latter is better because it is at this move not next move.

If you find the second approach acceptable, then the current version of Ogatak can almost achieve it. You can see the 'Paste SGF' option under the File menu, Ogatak also has a sidebar, and it even has the ability to save game collections ('save collection as') which allows you to save multiple comparisons in one file and restore the comparison process when opened next time. The only missing feature is the ability to copy the current SGF (note that this refers to copying the SGF string of the current board interface, not the SGF file itself). Therefore, it might be suggested to add the capability of copying the current SGF. For now, you can save it as a separate file and then open it, which at least eliminates the need for two GUIs
