I assume you are on the latest version of OpenTTD (1.10.3), is that correct? Both feature requests are also not implemented in JGRPP 0.34.4 (and by extension JGRPP 0.35.1).

Yes 1.10.3. I do not support JGRPP

Hi! Thanks for your interest in the project. To keep the issue list clear and focused, we generally don't keep feature requests here. As such I will be closing this. Other feature requests may go on the suggestions forum

I do like the train length in purchase list idea, though fitting it into an already very full window might be tricky...
