Howdy,
I've seen some suggestions about extending the data an asset issuer can give to their asset holders and potential buyers.
Since the core devs are super busy working on 1.9 and Ardor, it will not be a priority for them to include that now.
So I thought I'd make a plugin for now, and if there's interest, maybe the core devs can just snatch it and incorporate it into the core client at a later time.
This is work in progress, and this what I've done so far:

Features:
- News feed, asset issuer writes something and it pops up here. Stored as a prunable message, so it will be removed after 30'000 blocks (21 days) by default.
- Logo, stored in the data cloud by asset issuer. This will also be pruned by default.
- Custom asset info, stored as key + value on the asset issuer account. Stored as account properties and will remain until asset issuer removes them.
Only asset issuer can update this info btw.
Admittedly, front end layout is not my specialty, so there's definitely room for UI improvements. But what do you think of the basic idea?
