Cons
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
Con Not completely freeware
If you use MobaXterm at work, they hope you will pay for it. This isn't horrifying, but it's not providing any new features in Linux to warrant the outlay. Its integration with Putty in Windows as an X client may make it worth the funds.
Con Split screen prevents tabbed mode
If you split a screen within a tab, you have to go back to single screen before you can switch to another tab.
Con Can have some performance issues
MobaXterm can have some occasional performance issues. These happen rarely but it's worth mentioning that they exist, especially since this is a paid tool.
