Make "new windows" appear neatly

**Describe the bug**
The folder is opened in a new window (or a new window of any software). When the next file is often opened, it will easily appear on the other side of the screen, and it is also a different size from the previous window, which is not the same size as expected.
This "new window" jumping around can easily cause discomfort to the user

**To Reproduce**
Steps to reproduce the behavior:
1. Open any software. e.g. Terminal ,Falkon
2. Select the new window in the Top menu and repeat 2-7 times
3. See error

Or
1. Open from the hard disk'Startvolume' on the desktop.
2. Open the files one by one until this file e.g. :/usr/local/etc/devd/
3. See error

**Expected behavior**
It should be arranged neatly, no matter where the new window is moved, it can still be arranged neatly.
