Increment cell by dragging like in other office suites
Submitted by Nicolae Crefelean
So far I used a lot of MS Office versions, OpenOffice.org, LibreOffice.org, Kingsoft Office and a few others and all of them increment numeric cell values by dragging a single cell's "handler" to the right or to the bottom. If you drag it up or left the value will decrement.
Also, if you only want to copy that value to multiple cells, pressing Ctrl before releasing the mouse button will keep the same value for the whole interval. I thought this feature didn't exist in Gnumeric until I asked about it in the IRC channel. So it exists, but you have to add values to two cells and select them both when dragging the handler, so Gnumeric knows you want to increment the values.
For compatibility/usability reasons I would recommend the developers to tweak this feature to the existing behaviour in other office suites, but I have no idea how this would impact the current user base, so it's all up to the developers. At least now I know how to do it in Gnumeric.
