I use this to remap app keys:

    local appHotkeys = {}

    local function remapAppHotkey(appName, fromMods, fromKey, toMods, toKey, delay)
        if not appHotkeys[appName] then
            appHotkeys[appName] = {}
        end
        local hotkey = hs.hotkey.new(fromMods, fromKey, function()
            hs.eventtap.keyStroke(toMods, toKey, delay or 0)
        end)
        table.insert(appHotkeys[appName], hotkey)
    end
    
    local appWatcher = hs.application.watcher.new(function(appName, eventType)
        local hotkeys = appHotkeys[appName]
        if not hotkeys then return end
        for _, hotkey in ipairs(hotkeys) do
            if eventType == hs.application.watcher.activated then
                hotkey:enable()
            elseif eventType == hs.application.watcher.deactivated then
                hotkey:disable()
            end
        end
    end)
    
    appWatcher:start()

    -- Remap app hotkeys
    remapAppHotkey("Finder", { "cmd" }, "q", { "cmd" }, "w", 0.5)
    ... etc ...

Any particular reason for that? Are you using specific Linux APIs?

Just to clarify, this looks like a super helpful utility, something that I would personally use. The issue is that I noticed the installation instructions include a link to a prebuilt binary hosted on your website. Without providing access to the source code, you're asking users to trust executing an unknown binary on their system.

You should post a screenshot in the README to give people an idea of what the terminal looks like.

A few days ago I built https://github.com/overflowy/parallel-rsync to scratch my own itch: I realized I could just launch multiple rsync instances in parallel to speed things up.

Looks really expensive for a language learning app.

HTML and JavaScript serve distinct purposes, making better or worse comparisons logically flawed. Complex/interactive web apps requires JavaScript, period. Attempting to build sophisticated apps solely through HTML (looking at you HTMLX) eventually hits a functional ceiling.
