My CMS has a small window in which I can edit custom HTML/CSS. It can be expanded some, but not as much as I would like. It also displays all code as dark text on a white background. On a page where I am doing extensive custom coding, it is helpful to see it in a larger window and in a color-coded display so that I don't have to strain my eyes as hard. Especially when I'm trying to scan for specific elements and target issues and so that I don't have to scroll endlessly in a tiny window.
I like the macro feature for transforming text. For example, taking a CSV file of data and quickly turning it into a set of SQL "insert" statements. Also, useful for this is the find/replace feature using regular expressions such as taking a URL QueryString and breaking all the parameters into separate lines and perhaps sorting them for review.
This is a programmers tool. As such a lot of the features and benefits are lost on a non-technical user. To get the most out of the tool you need to have a basic crash course in how it works and what it can do. The documentation and community are good, but it takes a bit of time to get up to speed.
Never had to use their customer support before. There is ample documentation online so it's straightforward to find a solution to any problem you might encounter. For example, I needed to convert a string of HTML code to a properly formatted HTML file to "modify." Easy to do when there are so many users of the product who have needed to do that same thing before.
We've used both Notepad++ and Atom; both are great but nothing really beats the Sublime Text UI; super intuitive and friendly and does everything you need without overwhelming you with stuff you don't. Other options are free, but for our organization, it was well worth the small license cost for the persistent use of a great product.
When you want to quickly edit a file, TextPad starts up quickly and has many features over Microsoft Notepad. Visual Studio Code is an alternative in that it is full-featured and will edit text files but is slower at startup. I prefer the macro feature in TextPad due to its simplicity.
Sublime Text has helped me to focus on specific tasks, cutting out the clutter that many other IDEs have. As such, it has helped me be a more productive employee because I don't get dazed by hundreds of buttons. I can focus on just the code.
Sublime Text is so affordable that it's a no-brainer to have an extra tool in your toolset.
The Search features of Sublime Text are so useful that it has saved me a great amount of time compared to using Find & Replace menus in Xcode, Android Studio, or Eclipse.
