Cons
Con Not very powerful as far as text editing goes
nvALT's strength is its search feature. It has some basic text-editing features such as cut, paste, find-and-replace and so on. But it doesn't have any advanced text manipulation features available in other editors.
Con Frequent crashes in MacOS Sierra
aText crashes frequently, and the developer is unresponsive. Not clear if app is supported or under current development: last update was in 11/15; last post to aText Facebook page 10/15.
Con Doesn't work in Mojave
The current version, with no issues. In fact, I've never had any issue with it with Mojave, so I assume when Mojave was released, aText was already up to date for it.
Con Long time no update
Seems to be abandoned.
