Con Slow with input lag
Sadly, Electron strikes again. The input lag is noticeable and annoying. Startup also takes like 2 seconds or more (On an i7 from 2016 with SSD).
Con Some functions still fail
It's huge. The amount of resources it consumes is not justifiable.
Con Cannot remove the default profiles
For example, you installed Arch Linux for Windows Subsystem for Linux some time ago, but now you have deleted it and currently use Ubuntu on WSL. After that, if you decide to try this terminal emulator, you'll find Arch there without an option to remove the profiles already included in Terminus.
Con Easy to be confused with different brands of the same or similar name
Like Terminus (Russian production company), Terminus (font) or Termius (SSH client).
Con No multi window support
Can't split tabs into multiple windows.
Con Private keys needs to be managed on PuTTY
Since mRemoteNG is integrated with PuTTY (included in the installation), all private key needs to be configured on PuTTY itself and then the PuTTY session needs to be selected on mRemoteNG.
