I am a major user of Evernote, and I have not been backward in mentioning this, in the creation of my personal archive of knowledge. But I also use several of the other suite of program's that are so well linked into Evernote, like Skitch, and Penultimate, the later being the one I normally choose when I want to sketch out a detail.
I use it for working up ideas and details, like my timber cladding corner detail, I eventually used this to create a final detail.
The use of colour and the ability to erase and alter so easily is great, plus it saves direct to Evernote, and can be tagged along with other notes fora particular project.
Penultimate creates not one folder of ideas but as many as you need, as in today's photo of my part collection, I have many, each dedicated to a particular item, my house plans are plan, ideas room relations and layouts ideas I have, my general details are just that, ideas and actual instances.
I have often been with clients and one in particular wanted to do a lot of the construction himself, asked me whilst I was away about a detail, I made a sketch and sent it to him, coping myself, with the intension of drawing it later, but to my surprise, he was very happy in the response time, and the drawing, he understood it and went on building.
It takes some practice to use Penultimate, I use a small rubber pointed stick for fime work, but I have found that my finger can produce some great lines and textures, I then found a pencil topped with one of those little rubbers, I shaved a little of the top to make it pointed and now use this, saving £5 being the price of the special pencil advertised on an online Mac iPad store.
I am particularly pleased with my tree collection, I was making up a new tree set for a garden I was looking after, I wanted a different tree style, so after a few Penultimate trials I made up the one I wanted.
The CPD here I suppose is not the program, but the way I save ideas and thoughts, so often I use my Moleskin, it's mostly with me, but sometime I want just a little more, and if i have my iPad with me, penultimate is the tool of choice. The link to Evernote, the ability to take a screen shot, the way I can send via email.
