Geany is a nice text editor that can do a fair chunk of things proper IDEs can.

To add a terminal emulator to the messages pane you just need to install vte3.

To split the window, so that you can view two separate files simultaneously, you have to install a plug-in:

• geany/geany/blob/master/plugins/splitwindow.c

This seems to live in the big plug-in pack you can download too.

You can use the 'Send Selection to' function to send chunks of text to other programs for modification.

• Right-mouse > Format > Send Selection to > or
• Edit > Format > Send Selection to > or
• Ctrl+[n]

I have one setup that sends highlit text to sort when I press Ctrl+1, which alphabetises it. Nice for CSS.

Some ones I find useful:

You can enable .editorconfig support with a plug-in:

• editorconfig/editorconfig-geany
• editorconfig geany search.
