Optimal Layout 2 is a huge improvement over the first version. In version 1 I only used shortcuts to move windows around, as the window manager and grouping windows into groups etc. was too complicated for me. I constantly had to peek at shortcuts as I seldom used these features. All these features were just not sitting right in my workflow.
Optimal Layout 2 very nicely surfaces these features into a new, easy to use UI. To place windows quickly and precisely you can draw into a special area and the window jumps there (sounds strange, look at the dev's videos to understand). Very easy shortcuts help to save a window position you like and then recall this position for later use. You can access these features in multiple ways: either directly via shortcut, or via the window manager, or you can have icons representing the saved window positions in your menu bar on top and simply and quickly click on one of them. Great!
Over all I'm now using much more of the functionality of Optimal Layout, it's much easier to understand than the first version.
The only reason I'm not giving it a 5 star is because I like a feature other window managers are having that's missing in Optimal Layout. Other tools allow you to drag a window to the top edge which makes the window full screen, or to the top right edge to make the window fill the right half of the screen etc. If one could have hot areas (top screen, top right corner, right edge, bottom right corner, bottom edge, etc.) with Optimal Layout and drag windows onto these hot areas or hot corners and the window would fly to a programmed position, it would truly be feature complete for my personal use.
Great work in Optimal Layout 2! I like it a LOT!
