Cons
Con Not free
The subscription costs $89 per year.
Con No stable portable version
Any portable version present is wrapper. It moves files from portable folder to appdata and backward, which often cause dataloss
Con Cannot set text color for character under cursor to background color
Suppose you have a dark background with a light cursor and light foreground color: the light cursor will cover up whatever character it is on, so that you cannot read it. There is no option to set the foreground color for the character under the cursor to what is normally the background color. Such an option would allow you to read the character under the cursor.
Con Execution in xfce4-terminal - e mode is not always functional
Con Resizing text resizes window
Con No profiles
There's no profiles or profile-based customization in Xfce-terminal.
Con Can't scroll on spamming text
When text generates too fast, you can't scroll it, so you just can't read anything in such moments.
Con Does not support sixel images
