Auto-Position Block functionality available?

Within Xcos (v2026.0.0 under Windows 11), there is a menu command ‘Format→Auto-Position Block’, which doesn’t appear to do anything after selecting a block.

I would like this to work because I’m generating diagrams via a script and the block positions could be laid out rather randomly. This would come in useful.

Does the code exist for this action, or is it just a placeholder? Can someone point me in the direction of this source code section so I can take a look myself?

Thank you
