The data sources can be fetched by cron but it would be useful if there was a way to explicitly run a fetch on demand in the UI.
This is part of the plan. To implement this correctly an indicator like a progress bar would be needed, since some of these actions can take quite a while.
I have ported the Toaster progress bar and related background engine in separate derived project, so I will be able to port that into the SRTool. With that this will be easy to complete.
I have a working solution that I will post.
Released in recent refresh.
