This extension is currently work in progress. Consider this an alpha release.
quick-open-create makes it easy to open and create new files relative to the currently open one and browsing the directories without leaving the keyboard.
Add this to your keybindings.json, to open siblings etc easily with cmd+o or whatever floats your boat.
{
"command": "quickOpenCreate.open",
"key": "cmd+o"
}
quick-open-create will give you an easy way to show and and select the siblings of the current file to open it, or create a new one. This is really helpful when dealing with component based projects where you have related files next to each other. eg: scss, html, js and some config file.
