The amount of packages you can find on UiPath activity feeds is humongous, and it grows with each passing day. This can prove to be a nuisance when searching for a package with a more common name, for example. We felt your pain and decided to do something about this. From now on, all UiPath official activity packages can be easily filtered in the Package Manager so you’ll be able to reach your favorite package in no time!
