Settings files for Sublimetext, previous next tab and look

Setting files for Sublimetext are in this folder in Ubuntu: ~/.config/sublime-text-3/Packages/User

General settings
Insert this in ~/.config/sublime-text-3/Packages/User/Preferences.sublime-settings to change the skin, font size, tab size, convert tabs to spaces, etc. You might have to install the Solarized Color Scheme as a Package first:

{
  "color_scheme": "Packages/Solarized Color Scheme/Solarized (light).sublime-color-scheme",
  "font_size": 17,
  "hot_exit": false,
  "remember_open_files": false,
  "tab_size": 2,
  "translate_tabs_to_spaces": true
}

Previous Next tab
To get Firefox behavious, where Ctrl+Tab and Ctrl+Shift+Tab moves to next or previous tab, insert this in ~/.config/sublime-text-3/Packages/User/Default (Linux).sublime-keymap:

[
  { "keys": ["ctrl+tab"], "command": "next_view" },
  { "keys": ["ctrl+shift+tab"], "command": "prev_view" }
]

More font contrast
If you are using Solarized Light you can tweak the font colors by adding this file:

.config/sublime-text-3/Packages/User/Solarized (light).sublime-color-scheme

With these values:

{
    "variables":
    {
        "base01":  "hsl(194, 14%, 20%)",
        "base00":  "hsl(196, 13%, 25%)",
        "base1":   "hsl(180, 7%, 40%)",
    }
}
