This is how I would like the tool to work:
1. I click on "Scrape" and the tool starts running.
2. Two new buttons will appear - "Pause" and "Stop"
3. If I click on "Pause", the tool will pause and I can close down the tool. If I reopen it, I can click on a "Continue" button and the tool will continue scraping from where I paused it.
4. If I click on "Stop", a popup box will appear saying "Are you sure you want stop the tool?" and I can choose between Yes or No.
If I close the tool or it shut down for some reason, then next time I open the tool, it will have saved the data and I can click on "Continue", to continue scraping from where the tool stopped scraping.
