This is a crisper and more tightly written version than one previously submitted (and now deleted, because this is better).<p>There was one comment[0] on the previous submissions in which slvv[1] said:<p><pre><code> This kind of activity tracking and productivity management
is so helpful for students at a variety of levels. I wish
these skills were clearly and intentionally taught either
in high school or in early university! Even if everyone's
