I work with projects containing hundreds of files, but the current Project Files dialog makes it very hard to sift through the project files quickly.
I propose a "quick filter" that allows the user to type a string and filter out non-matching entries from the files table (this filter should not be confused with "file filters" that parse source files).
This is implemented in trunk, r7019.
Closed in the released version 3.1.9 of OmegaT.
