For a somewhat similar implementation (touchscreen is essentially handled as touchpad) look at how Teamviewer handles remote sessions to Windows desktop from smartphones.

I would really like any/all of those as a toggle-on mode for use on Android itself... selecting text with arthritis fingers is a pain – literally and figuratively.

The easiest approach is to just use a commonly available relay modules used with Arduino or similar platforms/microcontrollers, as they already contain minimum or all protection mechanisms. So, the module will contain the reversed diode in parallel with the relay, while additional transistor and optocoupler will allow you a complete galvanic isolation of the controlling- from the and relay circuit.

YouTube has plenty of user-friendly resources with schematics and functional overviews, just search for "relay module" or "relay arduino".

They have very low self-dishcharge rate (and even come precharged in packaging) and with recharge cycles ranging from 500 (for the highest capacity 2450 mAh AA ones) to up to 1000 (for 750 mAh AA/1900 mAh AAA ones). Also, they do not leak.

"3rd world country with a Gucci belt" is a rather popular one.

I've been looking for GUI launcher/software-catalog solution for Windows with those characteristics.

Still haven't found any.

Well, can't we build the similar addon and the crowd-sourced database, but one that would submit specific rule (page elements, and click order) to block everything - incl. "legitimate interest" bullshitery- except the barest of essential cookies?

Honestly, I'd donate certain amount every month and support the effort, if it was a very wide-service/website encompassing, and would give logical end-user easily/very customizable behaviours within options, easy for the everyday Joes, and that it wouldn't treat its power users as garbage.

And here's an idea for a starting recipe for every website: a library of set of actions that would run on the first visit and would result in decline/block for each and every cookie category and "partner" (and no, there is no such thing as "legitimate uses", GTFO), since most websites either roll their own ot customize some existing solutions (from what I see), but usually invert/dark pattern options and choices to a certain degree (usually "to hell").

I remember making a cursory search a year ago, and hardly found anything remarkable. (Might have been a case of Google's-bad-search-results syndrome.)
