Even though I don’t want to leave Dynalist I have been poking around at a few alternatives last week so I hope someone here provides some insight into their roadmap.
The closest thing I’ve found is Checkvist. It has tables and a kind of Gmail awareness, and also better Markdown support, hardcore keyboard navigation, and an active community. Other aspects I’m not crazy about though.
I’m also checking out GTDNext, since I’m using Dynalist for GTD, but it’s hardly a drop-in replacement, and the community isn’t very active so I’m not sure the project is going any where. BUT it is designed for GTD so I don’t have to figure out how to use a generic tool for that specific purpose and it ensures I’m not cheating.
I would love to give Moo.do more consideration but I feel like I would have to give up using Gmail and GCal directly and I’m not sure I’m ready to do that! Plus, they don’t have tables 
Also, Coda.io and Notion.so are awesome, but wouldn’t consider them to replace Dynalist. And, they don’t have simple tables like I’m looking for - only fancy spreadsheet/database tables. Honestly, Google should buy them both, put all their employees on the GDrive team, and finally come up with a worthy successor to Google Notebook (and competitor to OneNote, Evernote, etc).
