Matrix view: enable first matrix wider to see whole title #225
Description
In the Matrix view, the width of the first column allows only the first cca10 characters of the dataset title to be visible. This is impractical when working with larger numbers of complex datasets (e.g., combinations of cell type, treatment, concentration, or replicate), where this information is stored in the dataset title. Having to hover over each title to view the full text is inefficient. The ability to widen the first column - or optionally to implement more advanced grouping - would be useful.
