I agree. I'd love all normal paths be available as queue paths and vice-versa.
Also the red swirly path, the blue path, the tarmac path, brick and the hi gloss ones at least, are screaming to be re-colourable. I know it would involve a bit of work, but it would in effect, open the options for paths massively.
And as mentioned, being able to choose the railings between each path type would make the paths even more varied.
The cherry on the cake would be being able to choose any of the fences in the scenery/building tabs as the path railings. That would be amazing.
