Have you considered Microsoft's OneNote? Its freeform allows you to tailor it to your needs and your way of record keeping. And it allows to be shared among multiple people.
PS. FYI I am a PM at a top 100 fund
but your derogation of a small time investor is touching
Retail are unbelievable, social de-evolution appears complete.
No. You're unbelievable. I've made more in a year with pencil and paper than you'll probably make your entire life. Everything is a tool.

It sounds like a fetish of some sort. Software is a tool. If I am running a team of 2 myself included and Excel is sufficient, there is not reason for me to increase the number of dependencies and waste my time learning a new product. NASA has different requirements, different team size and, most important, different time constraints. In my case, need for rapid time to market and "discrematic" style of strategies makes for a very specific process that includes a lot of ad hoc work. Not something NASA would be doing.Enterprise software is built for the lowest common denominator of an organisation, if retail can access that same software out of the box, then they have an advantage over their competition. All smart entrepreneurs know this, which is why 99% of traders fail because they don't follow the efficiency, still can't believe you said you're a PM and don't understand collaboration, what a world. Given that you didn't even look at the pricing, launch a trial instance, you are basically clueless whether it works in your specific scenarios, companies like Nasa seem to think it does, however ignorance is bliss in the 21st Century and so de-evolution continues.
I actually found OneNote to be a great tool for close to the same thing you're talking about sle. And I really didn't want to like a msft product, but it's surprisingly good for putting some order to a bunch of disparate stuff while minimizing the time it takes to learn and use it. I started using it in grad school when I had a dozen ideas/inspirations/need to learn more about x type thing popping up every week, along with my regular workload, some of which fizzled out in a few days, some of which got picked back up a few months later, and a bunch of which were eventually turned into my first company. Still go back to it when I get busy enough to feel like I'm letting things drop through the cracks, especially ideas.Have you considered Microsoft's OneNote?

You feel the urge? 15-20% of what?Highly unlikely given when I feel the urge generate 15-20% per week, watch out for that pedestal though.
