There is only one but important difference between Texts in PO2013 and V4; it’s called Text Elements
Texts in V4 can not only contain text but also arbitrary elements offering whatever functionality you might find useful.

- The Fold elements you found already
- Version elements allow you to have different versions (e.g. Emulator1, Emulator2, FPGA) in the same source file
- Clock elements display the current time
- etc

Here a list of pre-built elements V4 offers:

I ported V4 text elements to Texts.Mod in PO2013 already.
The corresponding TextFrames.Mod needs a little longer...
As Texts is a fundamental module for the Oberon system, it needs to be tested thoroughly.
The code size of Texts and TextFrames will increase quite a bit. Most probably a 1 MB system is not well suited to include the V4 Text elements add-on...
