Geany is the PowerShell IDE of Linux
Geany is wonderful stuff. With libvte9 it becomes the PowerShell IDE of Linux.
Seriously, I use Geany as my shell for anything more complex than a one-liner I can type from memory.
Bind F8 to "send selection to terminal" to make it work like PowerShell IDE. It requires more key strokes than PSIDE, but it's close enough for productive script-writing.
