There were two things I spotted with the beta - first, when working on a picture, I found it very useful in the previous version to scroll through the command list and see the picture update as I scroll. In the new version the picture is only updated when I stop scrolling.
I think I see what you mean- when holding down an arrow key, in 2.3.7, the picture updates as each draw command is selected; in v3, it only updates when key is released. Is this what you mean?
I can look into that- I should be able to restore that behavior.
The second thing (and it's really minor) is that the increased font size and extra whitespace in the command list means you can't see as many entries
Not huge problems by any stretch, but I found the earlier version to be a little better in those respects at least.
I see what you mean. In v2.3.7 the font for forms and controls is MS Sans Serif and can't be changed. In v3, I have added the ability to change the font for forms and controls (which is the same font used for previewing logics, which can be changed on the Logics tab on the Settings dialog. The default is Consolas. I also restrict the available fonts to only mono-spaced fonts otherwise the preview text box won't work correctly. In addition to the Picture Editor draw commands list, other controls that use this font include the resource list, word editor, object editor, view editor list and several others.
The controls used in v3 also add some extra padding to the listbox items; not sure I can control that - it's a VS/C#/WinForms thing.
You could try choosing a different font/font size on the Settings dialog. Consolas at 10 pt or even 9 pt are a closer match to v2.3.7.
I could also see about using different fonts for the logic previews and forms/controls; then you could choose non-monospaced fonts for the forms and controls at a smaller size but still leave the preview logics as monospaced and at a different size as needed/desired. Let me know if you feel strongly about it and if so I'll see what I can do.
