gmail-sidebar-drive VS Traccar

1. List the files in order of last modified or last opened. This way I can list 25 latest files and go to the ones opened by me. (no folders needed, just the last opened ones).

2. With last modified date, tells me when the file was modified last. (useful if you collect data in sheets from forms or other stuff, tells you when you have a new lead). Also tells you when the colleague you share a file with has edited it or not.

I wanted to enhance it with adding more stuff like: show diff, so I know what has changed. And then, show the content from a doc right here in sidebar, because well it's easier to type a mail by looking at that.

I use https://www.traccar.org/ 👍

I suggest traccar - https://www.traccar.org/, open source and it's already complete with a server and web interface. Now you need a gps device, one that's supported by traccar - https://www.traccar.org/devices/. I suggest getting one that's capable of making http requests because it's easier to integrate with traccar (for this you'll need a sim card with data), compared to going with an SMS route where you need a way for your server to receive SMS texts.

Traccar I'm not as familiar with but seems like a promising vehicular oriented one https://www.traccar.org/

Spotlight on Traccar, a self-hosted, open-source platform for GPS device tracking

Open source GPS tracking platform - Traccar (https://www.traccar.org/). I think picking a small B2B niche is the best way to become successful. You're not going to be super rich, but you can have a good stable lifestyle business.

Since your title contains "Real-time" I assume gagamit kayo ng GPS, then might I also suggest traccar, https://www.traccar.org/, complete with server and client, easily integrated with OpenStreetMap
