I would also like to see a public roadmap, it would give me more insight on the features that are coming and let me know what you guys are currently working on.
I just read in a different topic that proper multi monitor support has been pushed back to 2.1 and that is a feature I would like to see implemented in Synergy, information like that could become more accessible if it were in a public roadmap. Also, the roadmap doesn't have to be definitive, you could also say we're working on these tasks for the next quarter but provide no order in them since that's quite fluid.
