You might also be interested in PropC-Online, which lets you program in raw PropC with instant feedback using the monaco editor instead of blocks.
My fork of Parallax Inc's Solo Propeller C Blockly Editor.
This was made out of pretty much frustration with features when using this for a school project and lack of raw propeller C access.
Dark Mode
Both the ace editor and blockly editors are in dark mode now.
code block
This block has been added to the blockly editor (system tab), which just inserts code (almost) inline, besides adding a new line.
Much smaller and easier to use than the regular User defined code block.
comment block
New comment block has been added, pretty much entirely cosmetic (saves space and is more obvious, however.)
Same as the Add 'comment' block, except gray and starts with //
