/skip All uses of style are purely functional and have nothing to do with thematic purposes, ie: setting the size and location of a popup modal according to input element size and cursor position, preventing default behavior of darkened background opacity on plugin modal popup as it conflicts with the intended purpose of the plugin (this happens only for my plugin and does not affect behavior for anything else).

let app: App;
You should not use global variables whenever possible, read here why: http://wiki.c2.com/?GlobalVariablesAreBad

app = this.app;
And specifically don't keep a global reference to the app object.

onunload() {
Instead of copy pasting this code use:
this.registerDomEvent(activeDocument, 'keyup', (event) => ...)

Also, your code won't work in popup windows.
See here how to update your plugin to support pop out windows:
https://obsidian.md/blog/how-to-update-plugins-to-support-pop-out-windows/

modalEl.style.position = 'fixed';, modalEl.style.maxHeight = '30px';
This should be moved to CSS.

Please let me know if there is anything else,
Thank you.
