Really, from ALL of the radio apps with built in stuff - I'm very happy to escape them. There are just too many issues - so it's better to leave Strawberry for music if you want a GUI Radio player.
With the way that, for example, BBC make it tough to track down URL's - and when you see the streams, it's easier to hunt down the prized OPUS ones and leave out the archaic mp3 or m4a streams... most music players can't keep up.
The website absolutely can, if a station stops playing then I go back to the browser and find the next stream.
I think I had one afternoon searching and finding stuff I liked on there, and it's really very trivial even for a grandmother - or even your wife.
However, the absolute best Radio GUI application IMO - the one I left behind (preferring the playlist) was Shortwave - which is something that Strawberry isn't ever going to come close to emulating...
It's very simple to look at, with BIG icons to click, and easy 'Browse' and 'Search'... though I found it only 95% reliable compared to the above website - which gives you the actual stream, so you can copy and paste it into your list.
Really, once she has a dozen stations - why would she need anything else hard-coded?
