Hello, Would it be possible to ask to remove trailing white space when pasting data in the "upload" tool ? Couple of times our users pasted text in the edit-box which contained trailing spaces (usually after copying the text from a web page) - and this confuses other tools (specially 'join'). If "Convert Spaces to Tab" is checked, an extra empty column is created. If "Convert spaces to tab" is not checked (e.g. when pasting a list of gene names, single column) - each name contains a space which is very hard to detect unless you know exactly what you're looking for. The attached patch removes those white spaces (I hope I found all the right places). -gordon
