Confirmed! I shall fix this for the next build. Thank you for letting me know!
The search is already there, above the buttons it says "Search:" and you can simply type in anything you want to show on the screen. If you click the Filter text, you will see even more search / filtering options.
It creates a snapshot and then monitors whether any new software is installed after that. But it cannot detect AviDemux, because of a bug within Uninstalr. Can you name any other software it failed to detect? If I can reproduce the problem, I can fix it.
Revo has a batch uninstall feature, yes, but it simply failed to automatically uninstall many software. In other words, it claims it can batch uninstall software, but in my testing, it just failed to do so.
In my opinion, both Revo and Hibit offer a very poor user experience and poor uninstallation performance and accuracy. If you are happy with the way they work, you should use them but I personally don't understand why people would use them.
In my test of Revo, it failed to automate the uninstallation of Blender, iTunes, Mailbird, Spotify, KMPlayer, Apple Mobile Device Support, AIMP, Internet Download Manager, IrfanView, Core Temp and Apple Software Update and it required user’s help in uninstalling these apps. Hibit uninstaller doesn't even support batch uninstall.
You can see Revo failing to perform an unattended batch uninstall here:
