Because none of the existing Sublime Text themes fitting my needs and design feel, I decided to make my own. Flatgrammer is the result of this decision. For me it was important to see which tab currently is active and that the sidebar shows the file as active too. I also clearly want to see in which file in an tab has unsaved edits, this is shown by an orange circle. For a better overview of the files in the sidebar, most of the filetypes got specific icons (this is only a Sublime Text 3 feature). The theme is downloadable via Github and available over Package Control. Feel free to create Github issues or to write some suggestions for improvement here in the comments.
