What Miranda, in my opinion, was missing all the time was support for soundpacks. If we could have a preconfigured set of sounds that just needs to be applied or could be changed at any time through Options, this would make it easier to get new sounds in case we get bored with our old sound set. Sometimes, soundpacks creators provided auto-exec files to apply their sets straight away, this was a very rare case though. What is needed in my opinion is standarisation of file names for sounds so that Miranda would always know what sound should be applied to an event if a pack is used. Of course this shouldn't stop advanced users from changing sounds within a set to custom files, but would be a nice addition for the lazy or less advanced ones who just want to switch their sounds to something different. For that, each plugin that offers sound events would have to register its sound names in the database.
