I realize this was a huge undertaking but what happened to the help files or rather the associated screens with information about the tool? Version 1.69 had some but version 1.70 has none, nada.
True. While one always has to filter out "for fun" remarks from what are genuine comments and concerns, the help from the tools that was already done and present in 1.6.x is gone in 1.7. And that I wouldn't label it as an improvement.
Again, leaving aside disgruntling remarks regarding the documentation, at this point in the maturity of the project, at least newly developed tools should be released along with their corresponding documentation. I'm not going to take a shortcut here - Juan, you have gotten used to put formal organized documentation as a VERY LOW priority thing, and as much as this is your baby and you take it to wherever you want following whatever your own thinking decides to take it, I think it's about time (it was a while ago) you make a habit to at the very least, slow down in the release of a new version that comes with new tools, until their, at least basic documentation is released along with those new tools. You're already spending the time creating the text in the rather descriptive tooltips, and sometimes that and just a bit more is all it takes to at least get the doc page of a given tool started.
Let me say this...
I much rather have the projects functionality live and working than if you had spent the time writing full docs for the whole application. Most people here probably feel the same. But I at least wouldn't have minded a bit of a wait if that's what it took to bring this application to the level of excellence that anyone would expect from a mature software like PixInsight. It seems as if it was really fun to develop a template/formatting framework for documentation, but then actually adding content to it was, well, boring and uninteresting... Thing is, even the most hardcore PixInsight's users will devour your documentation once it's written. Don't think it'd be useless or pointless. Nobody's asking for a quick fix to "learn PixInsight" here. At least I'm not and I believe I'm not alone.
I'll say it as I see it:
you're very inconsistent with the release of organized documentation within the software. I suggest you either step up and get it done, or don't do it at all, and be clear about that, but this "bits and pieces" approach to me reflects poorly in the overall impression of what today is the best astroimage processing application on the galaxy by far, regardless of whether one must have that to become fluent in using the software or not.
Since you like programming so much, you could start by writing an internal tool to extract tooltip text and generate raw documents explaining the parameters that can then be fed to the documentation repository or something, as a starting point. That's not probably what I'd do, but hey, whatever works.
And you know I tell you all this because "I love you man"... 8) (no, not THAT way)
As for the disgruntled comments, they'll continue to happen with or without documentation. That is not why the documentation should exists.
There it goes...
