I like to minimize my active projects. I want my project list to have only projects that I am really actively working on. But often a project has a prerequisite that means that after I turn my attention to it and commit to it, I can't really get started for quite some time. Less often (for me--it might be more often for others) a project will hit a block that will have it on hold for quite some time. For example, the project to update Widget App to version 88.5g of the underlying software requires that I obtain that software. Obtaining the software is likely to have enough steps to be a project of its own, a project that will take some time. (Fill out request form. Sign in blood. Obtain the broom of the Wicked Witch of the West. Defeat flying monkeys. And so on.) I suppose the most obvious solution, if I don't want blocked projects in my main project list, and I don't want them lurking there behind a filter, is to move those projects to some blocked project respository, sort of analogous to Someday/Maybe, to add a note specifying the prerequisites, and to check those projects regularly so that I don't miss them when they're unblocked. But does anyone handle this some other way?
