Please implement a "Refetch picon" button and place it next to "Reset icon" in Configuration -> Channel / EPG -> Channels.
Actually if I set picon first, and then upload it to the server, it does not show in Kodi. I know I can refetch all picons, but their URL changes then and Kodi also redownloads all of them.
What is more their IDs gets mixed and sometimes Kodi does not update some icons because it has them already downloaded. This leads to some channels having wrong icons.

I really miss the ability to update single icon.
