I hope this is the right list for this, as I saw in the archives there was
already some talk about the applet.
I have a habit (started by the same plasmoid) of going through comic from the
first one to the last one. I found it annoying having to wait for the next
strip to load, while most of the time I was reading and the network was free.
So I implemented a very simeple prefetching technique: When a strip is loaded,
the next one is requested from the engine. Since the engine uses caching, it is
immediately available upon pressing the "next" arrow.
I found if very useful and even included a patch for it against today's trunk.
I know the compilation is in some kind of a freeze so this may not be a good
time, but it might be useful to have in the next release.
