We will merge 0.45+ objects in the upcoming releases. If you can list what exactly they are that will greatly help in the process. The latency in their adoption is primarily to allow for them to be fully vetted for possible bugs and regressions.
Regarding storing text in a datastructure, I am not sure what that exactly means but I do use extensively something that may be similar, namely coll object from the cyclone library, which allows for a comprehensive storing, sorting, and recalling of data.
As for running pd-l2ork on other platfroms, until we complete the qt port, there is as of yet unadvertised
USB stick version you can download from L2Ork's site (see
http://l2ork.music.vt.edu/data/pd/ and look for a jumbo 6GB image--pd-l2ork would need to be updated to the latest version) that I tested with a reasonably large number of windows and OSX laptops with 90%+ success rate, with only select Dell and OSX machines refusing to boot it due to faulty EFI (whether intentional or unintentional), and some of the wifi cards not being supported out-of-box.
