In the Dolphin FIle Browser, right clicking then "Open With..." opens a window that allows you to set the default application for a mime type. However, this is quite inconvenient when the mime type is either incorrect/underspecified/missing for custom file extensions (often packages for specific applications that are just a zip file with a custom filename extension). Custom mimetypes can be configured in "File Associations - System Settings", but that's not as easily discoverable for newer users, and even for existing users it's annoying to go through "open with..." only to later realize the current file association is not what you want/expect. Causing you to have to *close out / backtrack* rather than *progress towards* the solution from a menu that promised to do just that. I can see 2 solutions to this: 1. In "Choose Application", link to "File Associations - System Settings", and let the user handle it from there. 2. Add a quick actions for creating/updating/adding to mimetypes directly in "Choose Application" SOFTWARE/OS VERSIONS Operating System: Kubuntu 25.10 KDE Plasma Version: 6.5.5 KDE Frameworks Version: 6.20.0 Qt Version: 6.9.2 Kernel Version: 6.17.0-8-generic (64-bit) Graphics Platform: X11 Processors: 16 × AMD Ryzen 7 5800X 8-Core Processor Memory: 32 GiB of RAM (31.3 GiB usable) Graphics Processor: llvmpipe
> 2. Add a quick actions for creating/updating/adding to mimetypes directly in "Choose Application" Seems to me like the better option. We already have the "Open with another application" dialog. Perhaps what we want is the ability to add application to mimetype association when you click on "show all installed applications". A button to open `kcmshell6 kcm_filetypes` for a mime-type seems also necessary as only there can you remove and change the association ordering.
