Is there any difference in functionality between the "[link: text|URL]" smart syntax links and "[text](URL)" Markdown-style links? Generated HTML seems to be the same, the only difference is the assistant dialog that pops up when you start typing "[link:", which does not happen for Markdown links.

"gg" description says "opens external links in a new window, Checkvist links in the current window". However, when I do "gg" from a global search, the focused list opens in a new tab. Maybe I'm using a wrong command? Is there another way to navigate to a list from global search?

Keyboard navigation is not available on the Active Lists page. Actually, the only shortcut I found working on that page is "?" for help.

Browser history navigation using Alt + Left/Right is disabled in Checkvist web. Firefox has an alternate shortcut Backspace/Shift+Backspace, but Shift+Backspace deletes an item or does nothing if no item is selected. Any suggestions?

How to make sure those red banner tips (example below) keep appearing time after time, not only the first time I do something?
