Cons
Con Uncertain future
The original developer, Tony Houghton, declared the death of Roxterm on 2016-05 at https://sourceforge.net/p/roxterm/discussion/422638/thread/60da6975/?limit=25#3fc9.
In 2018, work began to resume on Github rather than Sourceforge (https://github.com/realh/roxterm/issues/1) but the future maintenance is uncertain.
Con Not for regular users
ROXTerm is made for power users who spend most of their time on the terminal. For a regular user using ROXTerm it would be an overkill.
Con The official repository is inactive
The official repository for Wterm seems to be inactive, with open bug reports as far back as 2006.
