v10.0.0

A major version. The default theme is now your terminal's own colors, and alt+a alt+o alt+n in the statistics do something new on a row that's already in the filter.

Clear tags

• T X takes every tag off the editing list's copies of the cards in front of you. That's the cards picked with v, or else every card showing, so / and the statistics filter narrow it. There's no question first. u puts the tags back.

Statistics filter

• On a row that's already in the filter, alt+a, alt+o and alt+n switch it to that join, and the row keeps its place. The same key twice takes the row out, so alt+a alt+a always clears it.
• On the first row in the filter, AND and OR mean the same thing, so either one takes the row out.

Themes

• The default theme is now terminal: your terminal's own colors and background. If you never chose a theme, Tutor now looks like your terminal. ttr theme gruvbox brings back the old look.
• Any theme that paints its own background now sets the terminal's background to match while Tutor runs, and puts it back when you quit. In kitty, the strips at the window's top and bottom now match the theme. Before, they stayed the terminal's color.
