Can you clarify what problem you’re trying to solve? Can’t you just hit Ctrl+ Shift+T (open last file) to reopen the file if you accidentally closed it?
I can’t say I would find this a very helpful feature though I’m interested to know if others did.
Could you also clarify; would only the x close button of the file tab be disabled? Or would ALL means of closing a file be disable except Right click > close?
Of course I could re-open the tab, may be not through that combination (I wasn’t aware of that) but with recently close tabs.
Some times I have to many tabs and I start doing CTRL + W; I do that so many times and fast that I get to the point where I close some of my “always open” tabs
O may be I accidentally click on the “x”…
So instead to have the chance to close it and then bring it back some how, for me at least I would be much smooth to not close that tab. I think that if want it to close it I coud do right click > close
And I also think that instead of an “x” it should display a “pin”
