Cons
Con Windows-only
While it can run in Wine, it is native only to Windows. Linux users will have to use Notepadqq instead.
Con Settings confusingly scattered
Examples: try to change the tab size or used font.
Con Annoying update notifications upon start-up
Annoying update notifications tend to pop up upon start-up after not having used the app or machine for a few days. At the same time, they can be easily turned off.
Con Outdated UI
Only the text area can be themed, and it doesn't have as many features as browser-based text areas.
Con Limited new syntax support for new languages
It may be hard to find good plugins for relatively new languages.
Con Session backups not enabled by default
Unsaved tabs will be lost when Npp crashes, unless you first enable the session backup option.
Con User defined language doesn't support triple quote strings
It also doesn't support triple hashed comments. Both styles are overridden by their single character single line version.
Con Still missing some elementary text editor commands
Some gaps have to be filled by plugins, while these features should be built in.
For example:
- Jump to matching brace (bracket / parenthesis);
- Gutter selection of lines;
- Recall previous searches / replacements;
- Autofill of search field with text under caret (text has to be selected);
- Show whitespace / end of lines / indentation guides / right margin;
- Selection to upper / lower case;
and some more.
Con Problematic updater
Though the website says there is an update available, the updater in Brackets may give you an error, resulting in you having to download updates manually.

Con Slow
Con Supports only web languages by default <but>
Brackets is built for web development and that's where it excels at out of the box. Other languages that have a CodeMirror mode can be added as well.
<and language support plugins can be added>
