Has there been any progress on this? I switched to Remote Utilities Self-Hosted from the Free [censored] Control license because it allowed for more remote connections and I didn't need to rely on a third-parties infrastructure for my own personal/home/homelab remote access.
Having the ability to use forward/back buttons on a mouse as they would work natively on remove PCs seems like a fairly common feature. I use those buttons all the time in my day-to-day use of a PC.
Unfortunately, we cannot provide any specific ETA on the extra mouse buttons support yet, however, the feature is already added to our roadmap and will be definitely implemented in one of our future updates. We will do our best to make it available as soon as possible. Sorry for keeping you waiting!
