• Regression: Searching for File extension: PDF file *.pdf appears not to match files in sub-directories during Scan directory. ANY_FILE appears to work recursively

PDF Search

ANY_FILE Search

• Start directory and File extension controls should set a minimum height (overlap during resize)

• Allow search results control to be minimized (on resize). Minimum size is too large.

Import results list:

• Import result list columns should be resizable
• Re-order columns (Status | File | Message)
• Create one row for each file processes (test case: processing one file results in 7 rows, 6 of which are empty)
• Expand/Collapse triangle moves location when switching between Currently linked files and Import results. Both triangles for each list should be located on the left (not right)

UI & Usability Tweaks

• Search button should have a minimum horizontal size set
• Directory and File type controls minimum size is too large (labels disappear during resize)

Control Labels:

• Rename Scan directory button label to Search (consistent with dialog and feature title)
• Rename Start directory to Directory (remove colon :)
• Rename File extension: to File type (remove colon :)
• Rename Currently unlinked files to Search results

Unless this is an issue with windows java framework features (rather than file type static names set in JabRef)

• Rename ANY_FILE (*.*) to All files (*.*)
• Rename BIBTEX_DB to Bibtex Database (*.bib)

Control types

• Replace Select/Unselect Collapse/Expand buttons with right-click context menus
