I want to grasp the theory of microlocal analysis and apply this theory to some PDEs in $\mathbb{R}^n$. But most textbooks I found put much priority on manifolds. Sadly, I know little about them and don't really care about them. Also, I find that their analysis are beautifully but quantitative. I'm a man of classical PDEs and like estimates a lot. On the other hand, I'm also familiar with linear/nonlinear functional analysis. To sum up, I hope the textbooks:
1: pay a lot of attention to PDEs in $\mathbb{R}^n$ or bounded domains.
2: from the view points of functional analysis.
