I come from OSX and Coda. One of the most useful features it has is a smooth and functional autocomplete. Type “im” and the image tag is suggested. Press enter and the entire code for inserting an image is created. Now I’m sure this could be done via snippets, but I find autocomplete is a faster way and more versatile in many cases. Since you can have multiple choices displayed quickly and easily without memorizing hundreds of key combinations. What I think would be an excellent way of implementing it is to make it user created. Link the autocomplete in with the snippets implementation. So the user can create a snippet and its added to autocomplete as well. So instead of typing “lorem” and then “pressing tab” to insert a lorem ipsum paragraph. You could type “lorem” and different selections of lorem ipsum paragraphs could be available in a menu with a quick arrow or number pad keypress to insert the style you prefer. Another example would be with div. Type div and a menu would pop up with the option to insert “div id and div class”, “div id” or “div class”.
I hope my explanation made sense. I’m searching hard for a OSX replacement of Coda in Windows. But so far I’m fairly disappointed by the available options. Sublime seems like the first innovative editor I’ve come across.
