Moin!
I’m using Sublime text version 3.1.1 build 3176 on Mac OSX 10.13.6 and have huge problems with using Tabs and the project browser.
When I open a project initially open a couple of files everything is fine and every file I click on gets create a new tab. However after some time and some tabs open when I click on another file to it opens, but replaces a tab I already had open. Even on the triangle on the left side that file is now missing and when I click on the file from the replaced tab again it replaces the file I opened before to switch between them. This makes working with tabs really hard as I can’t get files I want to open together selected easily. I’ve now reverted to using the subl command line to open it, but there must be a way to select files form the project browser.
So long
