I think it was bernie who mentioned the need for terminal access in some cases, which seems valid to me. So, it allows activities too, but when it create/modify a journal entry it will activate the modal window again... From what i see in eben's comments, this modal window it is supposed to insist on unnecessary entries deletion, because is a critical moment. <div class="gmail_quote">On Wed, Dec 8, 2010 at 1:35 AM, Martin Abente <<a href="mailto:martin.abente.lahaye@gmail.com">martin.abente.lahaye@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"> Forgot to mention, activities are allowed ;).<div><div></div><div class="h5"> <div class="gmail_quote">On Tue, Dec 7, 2010 at 9:03 PM, Gary Martin <<a href="mailto:garycmartin@googlemail.com" target="_blank">garycmartin@googlemail.com</a>> wrote: <blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">Hi Martin, Hmmmm.... <div> On 7 Dec 2010, at 21:04, Martin Abente <<a href="mailto:martin.abente.lahaye@gmail.com" target="_blank">martin.abente.lahaye@gmail.com</a>> wrote: > Based on the comments from #630 > > When available space reaches the _PREEMPTIVE_SPACE_TRESHOLD > (75MB) a message notification will be displayed on every startup. > > When available space reaches the _SPACE_TRESHOLD (50MB) the > ModalaAlert will be displayed. > > Changes on the ModaAlert: > > * It will remain active until there is enough available space again. > * It will be deactivated when the journal is on the foreground > and it will be activated again otherwise. </div>So, as a coder who does use XOs for dev work, I'm stuck with this modal alert blocking my path while trying to use Terminal to access the filesystem to clean up some yum install that has got out of hand, or some git clone that's grabbed too much?
