I wanted to chime in in regards to some of things that could use some work:
1. The database-centric collaboration. I get that this might be a hassle to many, it took a few tries with me as you can see in the post history, at first I didn't even know what couchdb was, but as a Developer that has team members in different parts of the world, once I actually set it up, it just worked, no problem, me and my team were really excited once we started messing around with it and could see who was working on what. I get why he chose couchdb, though as a kind of less recognizable name for databases as other solutions, I was left scratching my head for a while, and asked myself why not have other options like SQL as people are more familiar with it. I don't think it's a hassle once you figure things out, and as an indie developer I would assume at least one person in your team would be tech savvy enough to figure it out in the end, because once you do, it is powerful. Sure if a better solution can be done, by all means, let's have them, maybe it's too much work, but having different ways to connect for team collaboration would be pretty cool.
2. I believe they are just meant to be a text database that you can pull from and keep an inventory of all items/quests in your game, I haven't touched it much, so I have to check it further to give you an honest opinion and feedback.
3. It is something we are getting used to yes, and I'm sure some improvements could be made. It is a design decision on baj's part, and I understand his reasoning, but we could polish this further
4. Documentation. I have to agree on this one, some videos are not working anymore on the documentation, it could really benefit from more written explanations as well.
Your localization suggestion sounds like it would be helpful yes, it would be cool if we had some features with localization in mind.
I have another suggestion if I may, I am used to using keyboard shortcuts to do my data manipulation, so i didn't really notice this at first. But I have team members that are more used to the right click menu approach, so it would be cool, if we could have the option to have both keyboard shortcuts and right click menu functionality.
