The frequency is what windows is controlling I've heard some tweaks can be made to really allow higher freqs.
For some other issues please see the new version. It has most of them. Like clock in sensors, saved scroll location and text with smaller spaces.
As for the history you already have it with ...

There should be a bit darker background in couple of new versions.

The new version has the alignment menu under Edit.

Hi Matt,
There are no any limitations or performance penalties on the size of individual circuit. The only consideration you should have is how easy to understand and observe your design.

Hi Matt,
Thanks for the suggestions.
I will try to implement the alignments, but it's better to keep your circuits small. They are more readable and easier to understand and verify.
As for copy of the truth table you can do right now. Just select all the content and hit Ctrl-C. To select you can ...
