It would be great if there was the possibility to open a file with the second application in the list with the applications for this file type on midclick on the file. Midclick on files has no function in dolphin. When I develop for the web, I want to open a file in the browser as well as in kate and so this feature would be quite useful.
This is a great idea. Right now, there is neither a hotkey nor a mouse click option, so it is relatively tedious to open a file with another application.
A possibly relevant merge request was started @ https://invent.kde.org/system/dolphin/-/merge_requests/596

I just realized that the implementation of this feature request broke the integration with Konqueror (and, I think, with any other application which embeds Dolphin part). For example, Konqueror used to preview the file in a new tab when the user middle-clicked on it. Now, it does nothing. I created a merge request (https://invent.kde.org/system/dolphin/-/merge_requests/691) attempting to restore the previous behavior when a Dolphin part is embedded in another application, while keeping the new one inside Dolphin.
