Echoing this to the plasma-devel list so that at least they're aware of the use-case (with apologies for top-replying to those who take offense).

If indeed each launcher is a separate plasmoid and each plasmoid has its own settings one could expect those to be saved in an application (pardon, plasmoid) specific rc file. If that is not the case that probably means that plasmoids don't run as individual processes but as are instead run (as scripts) by a host application (the plasma shell), and settings are stored in that host application's settings file.

I don't think it'd be very difficult to store individual plasmoid settings in such a way that they don't overwrite each other, given how the config file APIs are designed. In this particular case though it may well be that the launcher/kicker settings are stored for/under the plasmoid category instead of name so that you can change launchers and find most of your settings in the new one.

Even so that would evidently also apply to the icon setting, so my guess is that this is not being stored as a plasmoid property, but as a setting for how (where, etc) individual plasmoids are displayed. That still doesn't mean that the icon *has* to be reset (the other properties like launcher location don't, right?) but it seems a bit less surprising that it would be the case.

In short, I don't think it'd be a huge change to implement a sticky custom icon feature, but do think like Duncan that it will probably not be considered worth the effort (besides, do as the VDG tells you and use Breeze already ;) )

Duncan proposed the approach I also thought of, but that may not be feasible because of how settings files are used (typically rewritten as soon as you change something, and rarely if ever monitored for external changes). Apparently you (Franklin) change your launcher often enough for the icon issue to become one, so maybe there's yet another workaround. Myself I use Lancelot on my Plasma4 desktop, but sometimes need the standard kicker to save an updated session configuration. If that happens I just add the standard kicker to my secondary panel, and do what I want to do. If I needed this frequently I'd leave the kicker there.
You could try the same thing: add 1 or 2 additional launchers and set them to kickoff and/or kickerdash. With luck the plasma shell will remember all settings you configure for each of those launchers - if it doesn't you could probably report that as a bug that ought to be considered more seriously than your original issue.
