I'm actually not sure if the API supplies streak data.
I personally do not think this is the best place to put it. Now that I've made some improvements to the widget customization on the dashboard, why not add a Streaks widget there? Easier to get to, and would not disadvantage users who use streaks, but do not use the garden?
At the moment, I do not think I'll be adding info into the widget that replicates info elsewhere on the same page (schedules, heatmap), but I will whip up a widget with the streak info sooner than later!
(My method up till now has been clicking the permanent tab and searching the word "done" with control + F - obviously this is on pc. If the result is 4, I can relax. But I still messed up somehow and lost two nearly completed streaks )
Grammar and sentences still showing 0 in the "Terms to get correct" column for me (where it should have shown 5.) Words and kanji got a changed result.
Fixed all the visual stuff. Sentences ..looks like it's working. Grammar, better? It wasn't getting some of the other grammar types (like conjugation schedules).
