I was wondering/hoping that you would add a checkbox feature to Bike. One way I use outlines is to create a checklist for my students for their online courses. Having an actual checkbox option (along with maybe a legal numbering theme/option) would make Bike my sole outlining program.
Bike is working in that direction though maybe a while and not sure exactly where it will end up. I expect the next related feature will be inline formatting and ability to format “strikethrough” text.

If and when you do end up implementing a concept of “checked” items, a small feature idea here that I never realised I needed until I used outliners that offered it: “Pruning” checked items in either the whole document, or a specific row (and its children).
I use outlines extensively for managing projects and like to hold on to checked items for a while, but on a regular basis delete all checked items nested under a specific row to spring clean.
Until we get actual checkboxes, I am making do with a text expansion shortcut that inserts the 
︎ unicode symbol.

Thanks for the tip. That would work for me, but I doubt most of my students would find it easy enough to do. Plus, I generally convert the outline to a PDF that they can actually print and check-off each box (I know, very old-school analog).
Should be possible, I think, to write a script to toggle ☐☑ characters at the start of selected lines.
(I’ll take a look at the weekend)
In the meanwhile, if you just need a ☐ prefix for printing, you could toggle it on and off in selected lines by using an existing prefix-toggling script:
Here as a Keyboard Maestro macro:
BIKE - Toggle a box character prefix in selected lines.kmmacros.zip (2.4 KB)
and here as a JS script to attach to a keystroke in some other way:

(() => {
"use strict";
// Toggle a given prefix character in selected lines
// of Bike 1.2
// Rob Trew @2022
// Ver 0.01
// --------------------- OPTION ----------------------
// Which single-character prefix to add or clear ?
const
prefixChar = "☐";
// Application("Keyboard Maestro Engine")
// .getvariable("prefixChar");
// ------------ PREFIX CHARACTER TOGGLED -------------
// main :: IO ()
const main = () => {
const
bike = Application("Bike"),
doc = bike.documents.at(0);
return doc.exists() ? (() => {
const
selectedRows = doc.rows.where({
selected: true
}),
n = selectedRows.length;
return Boolean(n) ? (() => {
const [f, change] = (
selectedRows.at(0).name()
.startsWith(prefixChar)
) ? (
[dePrefixed(prefixChar), "CLEARED"]
) : [prefixed(prefixChar), "ADDED"];
return (
zipWith(row => s => row.name = s)(
selectedRows()
)(
selectedRows.name().map(f)
),
[
`${change} '${prefixChar}' prefix`,
`in ${n} selected lines.`
]
.join("\n")
);
})() : "No rows selected in Bike";
})() : "No documents open in Bike";
};
// -------------------- PREFIXES ---------------------
// prefixed :: Char -> String -> String
const prefixed = c =>
s => `${c} ${dePrefixed(c)(s)}`;
// dePrefixed :: Char -> String -> String
const dePrefixed = c =>
s => c === s[0] ? (
s.slice(" " === s[1] ? 2 : 1)
) : s;
// --------------------- GENERIC ---------------------
// zipWith :: (a -> b -> c) -> [a] -> [b] -> [c]
const zipWith = f =>
// A list constructed by zipping with a
// custom function, rather than with the
// default tuple constructor.
xs => ys => xs.map(
(x, i) => f(x)(ys[i])
).slice(
0, Math.min(xs.length, ys.length)
);
// MAIN
return main();
})();
