Thank you for the post.
For a full list of the documented changes to Layout Mode in FileMaker Pro 12, please refer to FileMaker's knowledge base article 10260:
The change to the shift-click behavior is mentioned in the article above. Thank you for providing additional clarification.
Additionally, if the goal of this post is to see this change reverted to the behavior in FileMaker Pro 11, then I would encourage you to enter this as a suggestion into our Feature Requests web form at:
These web form suggestions are monitored and read by our Development and Product Management departments and then discussed and considered for a future release. Although I could copy your post and paste it into the web form, there are some questions asked that only you can answer.
[This is the same comment I've just posted to the post 1/2 of this series, feel free not to read it. I must admit it looks a bit too corporatish to shell out copypasted texts; I hope this won't escalate.]
Thank you for this interesting document, but it seems that it is not relevant in this case. The document only talks about using the Shift key when resizing objects; I'm talking about moving objects. (I agree that using the Shift key to resize an object is no longer necessary, because objects now have side handles that do the same job.) The document does not mention constrained movement at all; I think it's an oversight and maybe this explains the sorry state of constrained movement in v12.
The document does mention dynamic guides, but these guides are not a substitute for constrained movement mode. The guides snap to other objects; the constrained movement mode is supposed to snap to the original position of the object being moved.
The document also mentions plain guides, and yes, these can be used to facilitate constrained movement, but this is way more complex. Assume I want to move an object strictly along the vertical axis. In v11 I simply drag it and hold the Shift key at any time to enter the constrained movement mode; this takes a fraction of a second. To use guides for this I have to do the following: show Rulers (a visit to the menu or a four-key shortcut), carefully drag a guide out of a ruler (carefully, because guides do not snap to anything, I need to position them precisely) and then start moving the object. Even if the rulers are already visible, dragging out a guide and positioning it exactly where I want it to be can take seconds and this is exactly what I'm takling about: in v12 I have to spend much more time to achieve the same result as in v11. First I thought twice as much, now I think more along at least four times as much.
Now let's assume FileMaker designers has planned a clever way to move an object strictly horizontally or strictly vertically and just forgot to tell us, and we, being far less clever, just fail to realize what it is. But the old way still kind of works! If you press the Shift key you do enter this constrained movement mode, except that it's much harder to do this the way you wanted! And if the old way is still sort of there and it is much worse than it used to be, how can it be not a bug?
I can submit this as a feature request, but a feature request must be something you're proud to talk about. Would you be proud to announce that you brought back something that otherwise haven't changed since v3? Some feature.
