I wholeheartedly agree about the discouraging rate of meaningful development of Layout.
I make thousands of pages of docs with Layout and, while it is better than any alternatives I have cone across, it is definitely not a top tier pro software, imho.
I wrote up a slew of posts a while back that suggested many substantive changes that would make all the difference in my day to day workload. And, for a short while, members of the development team were actively responding to my suggestions and even intimating that some of them were going to get fast tracked.
And now, maybe 1 1/2 years later, how many of these have occurred? Exactly none. Very discouraging.
And, for what it's worth, the changes to the leader text tool are horrible and I hate hate hate it's operation now. It truly is a crappy tool that takes an inordinate amount of time fussing with.
And the lack of ability to place dimensions on either side of the dimension lines (as works beautifully in SU) with a right click or keyboard shortcut wasted so much time over the course of a few years that it borders on the ridiculous.
And, for goodness sake, Layout just takes too darned many mouse clicks to do anything. The act of placing a dimension, moving the text to the end of the dimension line, edit the text, and then move on to the next takes something like 6-7 mouse clicks and an escape key click to boot. do that 200 times a day and there are hours wasted over the course of a week.
And that layout forgets what is active if you switch to another software and then come back is infuriating and again causes a myriad of unnecessary mouse clicks.
And, as you mentioned, the lack of a Ruby pipeline really holds the whole thing back. Imagine SU without plugins and I imagine a SU I couldn't use as my main software.
I could, and have, go on and on about this, but I know my words are completely wasted as nothing substantive will ever come from them. Do a search for OTB posts concerning LO if you care about my many many frustrations and appeals for improvement that didn't fall on deaf ears but obviously fell on ears incapable of actually doing anything about anything.
Makes you wonder what the development team is doing? Is it one guy sitting in a cubicle throwing darts at the wall? Come on Trimble; throw a bone to the Pro users!!!
