Would it make the configuration too complicated for new user to understand?
Looking at the current Panels area of the Preferences dialog, I don't think so. It currently says, in the area called "Double click":
Operation to perform on double click [combo box]
I would suggest changing it to
Operation to perform on double-click of file
in local panel [combo box]
in remote panel [combo box]
and I think that would be clear. I prefer adding the words "of file", as I don't think that it is obvious what it refers to at the moment. With this clarification, I don't think a new user would have difficulty.
Also, just a quick note: perhaps change the name of the area from "Double click" to "Double-click" [hyphenation]. (I know just how much of a nightmare it is to keep these things consistent! I write various technical articles and the phrase "double-click" is probably the single most irritating phrase of all; when I review them after writing the first draft I frequently find that I've used the hyphenated version and the unhyphenated version the same number of times in a single article!)
because I wouldn't normally choose Open, since that requires copying the file over first
So does editing :-)
:lol: indeed; it just the way my mind thinks about this! It's "obvious" that a remote file has to be copied locally in order to open it with an application on the local machine, but even though I know editing also occurs locally I still think of editing as happening "on the remote machine". It doesn't make much sense, I know!
Just another quick note about hyphenation in the Preferences dialog: in the "Commander" panel, in the "Panels" area, it says
Explorer style selection [combo box]
I found this a bit hard to understand at first glance. Then I realised that it should be
Explorer-style selection [combo box]
or, even better:
Use Explorer-style selection [combo box]
and perhaps if you don't mind the the combo box being wider it should list the options as
when using mouse and keyboard
when using mouse only
