As discussed in https://forum.kde.org/viewtopic.php?f=285&t=122478 it would benefit usability and consistency if more/all plasma applets would allow pinning, specifically the Application launchers and Widget explorer. By "more/all" I mean applets where this makes sense. This does of course make no sense for task/activity switcher(s). This makes sense for kickoff if you want to launch more applications at once or for the widget explorer if you want to add and align a widget / maybe remove one and add another one. Right now the widget explorer would close every time you select a widget which can be annoying. I selected general, because I cannot assign one bug to multiple components, if that is not the right behavior then mark this as invalid and I'll create individual bug reports for every component where this makes sense.
Who opens more than one app at a time? You'd have to: click kickoff click pin click app click app click unpin click kickoff As opposed to: click kickoff click app click kickoff click app You only get a saving if you open 4 applications at once, and even then I doubt I would remember to click the pin before clicking the first app.
David, you are partially right about the kickoff issue, but as you note yourself 4 is the number where it would add benefit (given all the applications are in favorites). I have to note though you considered the most simple case that supports your view best and did not consider all the movements in kickoff itself (other than the favorites category). For example: change to "applications tab", go for e.g. to "Education", then go to mathematics, then launch Kalgebra, but now we also want to launch KmPlot which is in the same category. Currently we would have to do all the former steps again.) I mean still you are right, for average users and most cases it wont add benefit, but it does not harm either, and we would have it for the special cases ;-). I do not know the code, is it a lot of work to add the pin functionality to an individual applet? If it is a lot of work, okay leaving out kickoff is arguably okay. But we certainly agree it is sensible for widget explorer, right? At least as sensible as for all other applets which currently have the pin functionality. If you do not like the general idea, would you be okay with an individual bug report against widget explorer component?
Sorry for this annoying second comment, but you also did not consider cursor movement: If the pin button would be sensibly placed in kickoff, it would be a lot less effort to go click pin, and in the end unpin, than "open application, move back cursor to menu button, navigate again ..." So in the end I think in case of kickoff this is simply a matter of opinion and view. I can understand the "WONTFIX" if it is that much work, that it can't be done in half an hour / 1 hour or if nobody cares to do that, but certainly not from argumentative standpoint.
