Total Commander

Currently the Synchronize Directories window is asymmetric: single click changes "unequal" to "from left" and the left part is the source for Asymmetric. It may be convenient to make this selectable, so that the first click changes "unequal" to "from right" and makes the right side the source for asymmetric.

For example, a small control nest to Asymmetric may be added. This would be in line with the ">>" control next to "by content".

Create a Button:

Command: %Commander_Path%\Totalcmd.exe /S=S:
Params: %X /L="%P" /R="%T"
ToolTip: Compare Absolute: L / R

Create another Button:

Command: %Commander_Path%\Totalcmd.exe /S=S:
Params: %x /L="%P" /R="%T"
ToolTip: Compare Source / Target

In the first instance, Compare tool will always show the Left/Right panel in the SyncTool as Left/Right.

In the second instance, Compare tool will show on the Left whichever panel is Source (active) when it's launched.
