So I worked on the drag feature for the window, that and the opening and closing as well.
I encountered a problem where the code refusing to run properly but after looking at it for a few minutes, I saw it was a variable naming error (probably from the guide, not really a major issue)
I made the handle a blackhole impression which the window is only moveable from that spot (the idea behind it is like a singularity pulling in the cursor and not wanting to let go, atleast thats what I want it to feel like)
The close button is also functional now and I made the underlined SpaceOS text at the top corner be what would open the welcome screen again. ohh, yes, there was this issue where after I closed and reopened the window, the positions will be all wrong and cluttered, I did a little search and found a fix for it by changing the display function from flex to block.
Ive also switched from inline CSS to external CSS file (although I had already used an external file for some earlier already.)
