While I don’t make use of the gesture functionality in my regular usage of Lemmy, my extensive usage of Lemmy Explorer made me think that swipe actions would be useful there too, whether it be to block communities as I typically use the list for, or subscribe or favorite communities for those who make frequent use of those functions.
Seeing today that Lemmy Explorer indeed has gestures implemented for it, my revised suggestion is that these gestures be mappable as is the case for other feeds in the app, as to make the gestures work from the left or right and have the option of disabling unused gesture actions.
The last update reorganized the Lemmy Explorer swipe actions a bit, but I will look into making them customizable. There are several areas I need to add support for customizable swipe actions, so this will probably be bundled with an update addressing all of those views.
