Or at least give a shortcut to reopen last, accidently closed tab, or give a function to remember the file name which closed last, because we could not identify which one we accidently closed while selecting one among multiple files, say in between 10 to 20 opened tabs.
We `Reopen Last Closed` command in `Ctrl + K` command palette. See https://www.sumatrapdfreader.org/docs/Command-Palette
As an inveterate tab-hoarder, I must say this is a great idea. A related much needed option is to copy Chrome's right click option for "Re-open last closed tab".
We have`Reopen Last Closed` command in `Ctrl + K` command palette. See https://www.sumatrapdfreader.org/docs/Command-Palette in latest pre-release
The request of the poster and the ideas of the commenters are wonderful, and I hope they will be implemented. As another solution, I think it would be good to have a “pin tab” option.
