It has been nearly nine months now since I abandoned using Dreamweaver and adopted Coda as my HTML/PHP editor and site manager. I never look back. Coda does have a few minor oddities about it, cases where I wonder why they did it that way, but I'm able to use it to do everything I need to with all of my blogs, associate stores, plain HTML sites and forums. My swearing while web editing has been reduced at least 90%.
One oddity I've noticed has to do with adding new files to your site. Assuming that you are creating, editing or otherwise manipulating these files on your Mac first, let's assume you add a new folder to a subfolder of document root, for example you might add a folder named "tiny" to an existing folder /images. If you select this new folder with the intention of uploading it to your site Coda will offer to upload it to the document root folder. I would have expected it to offer to upload it to the same folder on the server as it is in the local copy of the site. The simple fix for this unexpected behavior is to access the remote site in Coda, navigate to the folder that will contain your new upload, images in this case, then return to the local view of your site layout. Coda will now offer to upload the new folder to the desired location.
One of my websites is intended to provide support for people with celiac disease. On that site I'm using a number of different pieces of software plus some static and a few dynamic PHP pages of my own design. I'm using SMF in the forum, Associate-O-Matic in the store, Video Niche script to display YouTube videos, and Carp to show the content of RSS feeds. I wanted them all to look the same. I settled on an SMF theme that I really liked, then used Coda to force feed the layout into all of the other pieces of software. I'm rather pleased with the results, see what you think. The CSS editor built in to Coda was immensely helpful in this project.
When editing files Coda behaves exactly as I would want it to, it is a well designed, stable, well supported program and I'm abundantly pleased with it. No more Dreamwrecker swearing at this house. Coda gets 5 stars!
